LAN FEATURES

ENR1504 Features

Four 10/100 Ethernet Ports:

4-port dual-speed

(10/100 Mbps) fast Ethernet switch allows you to create

or extend your LAN.

The Uniden ENR1504 10/100 Ethernet Cable/DSL Router

provides many easy-to-use advanced features, described

below.

Auto MDI/MDI-X: Accepts both straight-through and

crossover networking cables, avoiding the confusion of

which type of cable is necessary.

INTERNET ACCESS FEATURES

DSL & Cable Modem Compatible: Allows you to

connect to either DSL or Cable modems with Ethernet

supported.

ROUTER/SECURITY FEATURES

Share High-Speed Internet Access: Your ISP gives

you a single WAN IP Address that can be shared among

all computers connected to the LAN. This is known as

a Private Network. The computers connected to the

router (LAN) are hidden from the Internet. This process

is called Network Address Translation or NAT.

DHCP Server: Dynamic Host Configuration Protocol

(DHCP) automatically issues LAN IP Addresses to PCs

and other Internet devices on your LAN.

NAT Protection: Network Address Translation (NAT)

allows all LAN computers to share a single WAN IP

Address while hiding all LAN computers from external

sources.

PPPoE Support: The ENR1504 supports Point-to-

Point Protocol over Ethernet or PPPoE. If you use a

cable modem or DSL to connect to the Internet, you may

need this feature enabled.

Stateful Packet Inspection: All Stateful Internet

Sessions (i.e. TCP) are monitored for malicious and

erroneous packets, protecting your network from

hackers.

Keep-Alive: When you use a PPPoE account, your ISP

may disconnect your PC if it remains inactive for a long

period of time. The keep-alive feature sends a data

packet over the connection at a designated time interval

to make sure the Internet connection remains active.

DoS Protection: Denial of Service (DoS) attacks

overload your router with invalid packets and connection

requests, using so many resources that your router

crashes and Internet access is no longer available.

The ENR1504 protects against DoS attacks.

Dial-on-Demand: For PPPoE accounts, this feature

activates the Internet connection during the boot-up

stage, or only when using the applications which require

Internet access, such as Internet Explorer.

CONFIGURATION & MANAGEMENT FEATURES

Static or Dynamic IP Address: Supports both Static

and Dynamic IP Addresses provided by your ISP.

Web-Based Configuration: No software installation is

required to configure the Router

Download from Www.Somanuals.com. All Manuals Search And Download.

Remote Management: Any computer on the LAN can

connect and configure the ENR1504.

LAN Activity Log: Keeps track of all activity and

attacks on your network. This activity log can be sent to

you via e-mail hourly, daily, weekly or however you want

to review your LAN activity.

Password Protected Configuration Utility:

The

configuration utility is password protected, preventing

unauthorized users from modifying the feature settings.

DNS Server: Supports 2 Domain Name Service (DNS)

Servers to relay DNS entries. This speeds up Internet

connections.

PARENTAL CONTROL FEATURES

Internet Access Control: Allows you to enable or

disable any computer on the LAN from accessing the

Internet; you can also determine when and how long

individual computers have access to the Internet.

Key Word Filtering: Allows you to include or exclude

a list of key words specified for a web address (URL)

and/or that reside on the web site.

ADVANCED ROUTER FEATURES

VPN Support: The router passes through Virtual

Private Networking (VPN) connections, so it can support

VPNs that use IPSec, L2TP and PPTP without any user

configuration.

Online Conferencing Support: Supports Internet

Telephony and Conferencing programs.

DMZ: Allows the Internet unrestricted access to one

computer within your LAN. This allows you to run

programs that are incompatible with firewalls.

Port Mapping:

Allows Internet users to access

Internet servers on your LAN. This allows you to

support a web server or other host from within the

firewall.

reboot, similar to turning the power on and off. However,

if you press and hold the button for approximately 10

seconds, the device will reset to the factory default

settings, erasing any configuration changes you have

made (including the password).

1. Hardware Installation: Through this process you will

physically connect your computers to your router.

2. PC Configuration: For each computer, you will need to

make sure they have the same LAN IP Address (The LAN IP

Address is similar to an area code for making telephone calls.

In order for all the computers to talk to each other, they must

reside in the same area code).

Ports 1 through 4: These auto-sensing 10/100

Ethernet RJ-45 Jacks ports automatically detect the

speed of any attached Ethernet device and provide a the

correct Ethernet connection. All of these ports are

configured with auto MDI/MDI-X, so they support either

straight or crossover cables, (Cat 5 UTP). Each port

supports a maximum cable length of 100 meters over

category 5 twisted pair cable.

3. Basic Router Configuration: Within this step you can set

your Parental Controls, Passwords, and other features of

your 10/100 Router.

WAN Port: RJ-45 Interface connects to either the DSL

or Cable modem.

STEP 1: HARDWARE INSTALLATION

7.5V Power Jack: Connects to the Uniden supplied

external power adapter to the power jack.

NOTE: During the hardware installation process, please

make sure all computers and the router are turned

off until the installation process is complete.

Before installing the ENR1504 you will need the following:

One external DSL or Cable modem with an Ethernet

Port.

Network Cables with RJ-45 connectors (UTP CAT 5).

TCP/IP network protocols installed on all PCs. (See

page 85 if you need assistance)

Download from Www.Somanuals.com. All Manuals Search And Download.

INSTALLING THE HARDWARE

STEP 2: PC CONFIGURATION

4. Connect to the DSL/Cable Modem: Connect one end of

the supplied CAT 5 network cable to the DSL/Cable Modem.

Insert the other end into the ENR1504 port labeled WAN.

In order for your computer to communicate with the ENR1504,

both devices must be on the same LAN, i.e. the first three parts

of their IP addresses must be the same:

5. Connect to the PC’s: Using standard CAT 5 network

cables, connect any one of the four available LAN ports

(labeled 1 through 4) to your PC’s network card or Ethernet

connection (RJ-45 jack).

The default IP address of the ENR1504 Router is 192.168.1.1.

As a result, your PC’s IP address must start with 192.168.1 as

well. Fill in the last digit with some number other than 1 to

distinguish your computer from the router.

6. Power on the Router: Plug the power adapter into an AC

power outlet and connect the power supply to the power jack

on the rear of the ENR1504. The power LED should

immediately turn on.

To verify and/or change your PC’s IP address so it is on the

same network, please see the instructions specifically for your

Microsoft operating system: Windows 95, 98, ME, NT, 2000 or

XP.

NOTE: The ENR1504 has no “on” switch. It will power on as

soon as the power adapter is connected.

NOTES:

7. Observe the Power-On Self Test: When the ENR1504

powers on, it conducts a series of hardware diagnostics

called Power-On-Self-Test (POST). While the POST is

running, watch the front panel of the router. The Test LED

should stay ON during the POST. If router passes the

POST, the Test LED will turn off. If the Test LED stays on,

then the router has failed the test.

If you are using the default ENR1504 settings and

the default Windows “Obtain an IP address

automatically” (DHCP) settings, no changes are

required.

By default, the 10/100 Router will act as a DHCP

Server, automatically providing an IP Address and

other related information to each PC on the LAN

when that PC boots up.

The hardware installation is complete. Continue to Step 2: PC

Configuration on page 16.

If you receive a Static (Fixed) IP address from your

Cable/DSL provider, write it down along with your

DNS Server information when prompted through the

steps below. You will need to enter the Static IP

address later during the IP Sharing Section of the

Owner’s Manual.

management/configuration interface. Although the router’s

default settings allow most users to connect with no further

configuration, you will need to set the password, time zone, and

any desired parental access control rules. In some cases, you

may have to change a few of the communications settings to

connect to your ISP.

If none of these conditions apply to you, then the basic

configuration should be all you need. Even if you do need

advanced configuration, you will need to perform the basic

configuration as the first steps of an advanced configuration.

LOGGING IN

Your router will require more advanced configuration if any of the

following conditions apply:

Before starting, be sure your computer is correctly configured to

obtain an IP address automatically in the TCP/IP networking

setup. If you have any trouble communicating with the

CONFIGURING BASIC ISP CONNECTIONS

In many cases, you will be able to connect to your ISP without

adjusting any of your router’s communication settings.

However, if your ISP assigns you a domain name or URL

(e.g.,jonesfamily.net) or if your ISP tells you to communicate with

a particular Domain Name System (DNS) server, you will need to

enter this information into the router. (A DNS server translates

the domain name or URL into the numeric designation—or IP

address—of the computer that maintains that web site.)

Figure 11 WAN Configuration, Dynamic IP Screen

To correctly configure the router to connect to the Internet, you

may need the following information from your ISP:

(You can also configure the router to automatically

obtain the DNS server address from your ISP.)

4. Under the DNS Server fields, select Auto to have the router

automatically obtain the DNS server information from your

ISP. Select Manual if you want to enter DNS server

information by hand.

Advanced Router Configuration

For most users, the default settings of the router are exactly what

they need; there is no reason for them go beyond the basic

configuration we’ve already discussed. However, if one of the

following conditions applies to your PC and network, you will

need to delve into the more advanced configuration options of

the router:

NOTE: If the router does not prompt you to reboot it at the

end of the last configuration step, use the reboot

command. See Rebooting the Router on page 77.

Your ISP gives you a static IP address.

Your ISP requires PPPoE support.

Your ISP requires you to have a specific MAC or

hardware address to connect to the network (MAC

address spoofing).

You want to make sure a particular PC (e.g., a mail

server or a web host) always gets the same IP address.

You need to run an Internet server or a web host from

within the firewall (port mapping function).

You want to use the Universal Plug and Play feature

(UPnP).

You have programs that must operate outside the

firewall (DMZ function).

You want to block an external PC from communicating

with your network (MAC address blocking).

You need to configure the router’s DHCP settings or

configure the router to operate within a LAN that has an

existing DHCP server.

You want to route or block data based on information in

each individual data packet (packet filtering feature).

You want to link your router to a dynamic DNS service.

CONFIGURING FOR A STATIC IP ADDRESS

Follow the procedure below if your ISP provided you with a static

IP address. If your ISP gave you a four-part number as “your

address,” it is probably a static IP address. If your ISP did not

give you an IP address at all, you do not have a static IP address.

If you are not sure if you have a static IP address or what it might

be, contact your ISP.

To complete this configuration process, you will need the

following information from your ISP:

Your static IP address (a four-part number separated by

dots or periods)

CONFIGURING A FIXED IP ADDRESS FOR A PC

Most of the time, you want to let the router automatically assign

IP addresses to computers that connect to it using Dynamic Host

control Protocol or DHCP. In some cases—for instance, a mail

server, a web host, or a computer that operates as the

DMZ—you need to make sure that a PC always receives the

same IP address.

Figure 15 DHCP Server Screen

RESERVING FIXED IP ADDRESSES

3. In the DHCP client list at the bottom of the screen, identify

the computer you want to assign the fixed IP address to.

Copy down the PC’s IP address and MAC address. If you

have not yet connected the PC, identify an unused IP

address to reserve for the fixed IP address computer.

If the PC supports DHCP, follow the steps below to configure the

router to always give the same IP address to that PC:

If the PC does not support DHCP, you will need to manually

configure the IP address on that PC and then make sure that the

DHCP server never assigns that IP address. If you add the

address in the DHCP server’s “exclude” table, we can make sure

the router never assigns that IP address.

Follow the steps below to configure the router to exclude the IP

address assigned to the PC:

1. At the PC, manually configure the IP address. Record the

IP address.

2. Open a browser window and login to the router.

CONFIGURING A PC AS A HOST (PORT MAPPING)

Figure 18 DHCP, Excluded IP Table Screen

The Internet uses ports to specify different types of service

requests. For instance, an email message contains a code for

port 110 (POP3 mail services) while a web page request

contains a code for port 80 (HTTP services). This allows the

router to send the requests to the correct host: any marked as

port 110 is routed to the mail server, and any data marked as

port 80 is routed to the web server.

4. Click the Add button at the bottom of the screen. This

displays the Add Excluded IP screen. (See Figure 19.)

If you want to set up one or more PCs as a host, you must tell the

router what services should be sent to that host. This

configuration is called port mapping. TCP/IP, the Internet

protocol standard, has over four thousand ports defined for

different services.

Of these, about one thousand are

considered “well-known” ports; these are the ports used most

often. Table 2 lists just a few of the most commonly needed

well-known ports. (Complete lists of all well-known ports are

readily available online; simply do a web site search for

“well-known ports”.)

CONFIGURING UNIVERSAL PLUG AND PLAY (UPnP)

Universal Plug and Play or UPnP is a networking architecture

that provides compatibility among computers, networking

equipment, software and peripherals. With UPnP, connected

devices communicate their features to the network at a times

interval so other devices can access those features.

NOTE: If the router does not prompt you to reboot it at the

end of the last configuration step, use the reboot

command. See Rebooting the Router on page 77.

Follow the steps below to configure UPnP support:

1. Open a browser window and login to the router.

CONFIGURING A DMZ

The router allows you to configure a single PC on the LAN to be

forwarded all traffic received on the Firewalls WAN interface. If

you want a PC to receive all Internet traffic unfiltered from the

Internet then they should be configured as the DMZ. Follow the

steps below if you need to configure a PC to operate as a DMZ.

2. Click Advanced Configuration, then UPnP. This displays

the UPnP Setup screen (see Figure 22).

NOTE: Any PC that is configured to operate as the DMZ is

not protected from malicious access by the router.

NOTE: Though a DMZ is set up to receive all traffic

unfiltered by the firewall, traffic is still subject to

translation by NAT. This means that Applications

that are damaged by NAT (i.e. SIP) will still be

affected.

The ENR1504 router can act as a DHCP server, so it can provide

IP addresses to computers on your network. By default, the

DHCP server function is enabled. In most cases, the default

settings will serve your network just fine. However, you will

have to change the DHCP settings if the following conditions

apply:

If you want more control over which IP addresses the

router assigns and how long those addresses are valid.

ENABLING DYNAMIC DNS

A Domain Name System (DNS) server maintains a list of Internet

addresses and URLs (web addresses) and the IP address of the

computer that maintains the website. Usually, the IP address

for the host computer must be static. A dynamic DNS service

provides an alias for host computer that have dynamic IP

addresses.

You should enable the dynamic DNS feature if you have a

dynamic IP address from you ISP and you want to maintain an

Internet host on your network. Follow the steps below to enable

dynamic DNS:

Follow the steps below to edit the routing table:

1. Open a browser window and login to the router.

2. Click Advanced Configuration, then Routing Table. This

displays the Routing Table screen (see Figure 28).

EDITING THE ROUTING TABLE

To provide Internet access, the router must be able to contact all

the PCs on your network. If all the PCs on your network are

directly attached to the router, the router always knows where

they are. However, if a PC is attached to the router through an

intermediary device (such as another router or another PC), the

router cannot find it. These intermediate devices are called a

gateway, because they serve a gate between the router and the

remote PC.

The routing table tells the router which gateway devices these

remote PCs or networks are connected to. Maintaining the

routing table lets the router know which gateway device to send

a data packet to reach a remote PC. You may have to edit the

routing table if the following conditions apply:

CONFIGURING PACKET FILTERING

Packet filtering allows you to route or block data based on

information in each individual data packet. For example, if you

want to allow only email from a particular server and block all

other traffic, you can configure the router to allow only those

packets that come in on the mail protocol ports (see Table 2 on

page 51 for a few of the most commonly needed well-known

ports). Follow the steps below to configure packet filtering:

4. Under the Network Address field, enter the IP address of

the remote PC or network you want to configure a route for.

Be sure to enter the four separate parts of the IP address

into the four separate boxes in the field.

5. Under the Subnet Mask field, enter a subnet mask for the

remote PC you entered above. If you are providing the

route for a specific PC then the subnet mask of the PC

should be 255.255.255.255. Otherwise a subnet mask

indicating the size of the network should be used. Be sure

to enter the four separate parts of the subnet mask into the

four separate boxes in the field.

1. Open a browser window and login to the router.

2. In the menu at the left side of the screen, click Firewall

Security and then Packet Filtering. This displays the

Packet Filtering screen (see Figure 30).

and interact with all the information on the World Wide Web or

PC. The word “browser” seems to have originated prior to the

Web as a generic term for user interfaces that let you browse text

files online.

automatically sends a new IP address when a computer is

plugged into a different place in the network.

DHCP uses the concept of a “lease” or amount of time that a

given IP address will be valid for a computer. The lease time

can vary depending on how long a user is likely to require the

Internet connection at a particular location. It’s especially useful

in education and other environments where users change

frequently. Using very short leases, DHCP can dynamically

reconfigure networks in which there are more computers than

there are available IP addresses.

Cable Modem – A device that connects a computer to the cable

television network, which in turn connects to the Internet. Once

connected, cable modem users have a continuous connection to

the Internet. Cable modems feature asymmetric transfer rates:

around 36 Mbps downstream (from the Internet to the computer),

and from 200 Kbps to 2 Mbps upstream (from the computer to

the Internet).

DHCP supports static addresses for computers containing Web

servers that need a permanent IP address.

Data Packet - One frame in a packet-switched message. Most

data communication is based on dividing the transmitted

message into packets.

For example, an Ethernet packet can be from 64 to 1518 bytes in

length.

DNS - The Domain Name System (DNS) is the way that Internet

domain names are located and translated into an Internet

Protocol (IP) address. A domain name is a meaningful and

easy-to-remember “handle” for an Internet address.

Default Gateway - The routing device used to forward all traffic

that is not addressed to a station within the local subnet.

Domain - A sub network comprised of a group of clients and

servers under the control of one security database. Dividing

LANs into domains improves performance and security.

DHCP (Dynamic Host Configuration Protocol) - A protocol that

lets network administrators centrally manage and automate the

assignment of Internet Protocol (IP) addresses in an

organization’s network. Using the Internet’s set of protocol

(TCP/IP), each machine that can connect to the Internet needs a

unique IP address. When an organization sets up its computer

users with a connection to the Internet, an IP address must be

assigned to each machine. Without DHCP, the IP address

must be entered manually at each computer and, if computers

move to another location in another part of the network, a new IP

address must be entered. DHCP lets a network administrator

supervise and distribute IP addresses from a central point and

Download - To receive a file transmitted over a network. In a

communications session, download means receive, and upload

means transmit.

Driver - A software module that provides an interface between a

network interface card and the upper-layer protocol software

running in the computer; it is designed for a specific adapter, and

is installed during the setup of the adapter.

DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a

redundant bit pattern for each bit transmitted. This bit pattern is

called a chip (or chipping code). The longer the chip, the

greater the probability that the original data can be recovered.

Even if one or more bits in the chip are damaged during

transmission, statistical techniques embedded in the radio can

recover the original data without the need for retransmission.

To an unintended receiver, DSSS appears as low power

be known as the software.

communications circuits.

For example, it can adjust for

overloaded traffic or failing lines and is much more flexible than

static routing, which uses a fixed forwarding path.

data is placed on and retrieved from a common transmission

medium. Has a transfer rate of 10 Mbps. Forms the

underlying transport vehicle used by several upper-level

protocols, including TCP/IP and XNS.

associated devices that share a common communications line

and typically share the resources of a single processor or server

within a small geographic area (for example, within an office

building).

IP Address - In the most widely installed level of the Internet

Protocol (IP) today, and IP address is a 32-binary digit number

that identifies each sender or receiver of information that is sent

in packets across the Internet. When you request an HTML

page or send e-mail, the Internet Protocol part of TCP/IP

includes your IP address in the message (actually, in each of the

packets if more than one is required) and sends it to the IP

address that is obtained by looking up the domain name in the

Uniform Resource Locator you requested or in the e-mail

address you’re sending a note to. At the other end, the recipient

can see the IP address of the Web page requestor or the e-mail

sender and can respond by sending another message using the

IP address it received.

Latency - The time delay between when the first bit of a packet

is received and the last bit is forwarded.

Link Quality - The quality of data being received.

MAC Address (Media Access Control Address) - A unique

number assigned by the manufacturer to any Ethernet

networking device, such as a network adapter, that allows the

network to identify it at the hardware level.

IPCONFIG – A utility that provides for querying, defining and

managing IP addresses within a network. This utility is

commonly used under Windows NT and 2000, for configuring

networks with a static IP address.

unit of measurement of the speed of data transmission.

NAT (Network Address Translation) – The translation of an

Internet Protocol address (IP address) used within one network

to a different IP address known within another network. One

network is designated the inside network and the other is the

outside.

Packet Filtering - Discarding unwanted network traffic based on

its originating address or range of addresses or its type (e-mail,

file transfer, etc.).

Port – A pathway into and out of the computer of a network

device such as a switch or router. For example, the serial and

parallel ports on a personal computer are external sockets for

plugging in communications lines, modems, and printers.

PCI (Peripheral Component Interconnect) – A peripheral bus

commonly used in PCs, Macintoshes and workstations. It was

designed primarily by Intel and first appeared on PCs in late

1993. PCI provides a high-speed data path between the CPU

and peripheral devices (video, disk, network, etc.). There are

typically three of four PCI slots on the motherboard. In a

Pentium PC, there is generally a mix of PCI and ISA slots or PCI

and EISA slots. Early on, the PCI bus was known as a “local

bus.” PCI allows IRQs to be shared, which helps to solve the

problem of limited IRQs available on a PC. For example, if

there were only one IRQ left over after ISA devices were given

their required IRQs, all PCI devices could share it. In a PCI-only

machine, there cannot be insufficient IRQs, as all can be shared.

PPPoE (Point to Point Protocol over Ethernet) – A method used

mostly by DSL providers for connecting personal computers to a

broadband modem for Internet access. It is similar to how a

dial-up connection works but at higher

PPTP (Point-to-Point Tunneling Protocol) – A protocol (set of

communication rules) that allows corporations to extend their

own corporate network through private “tunnels” over the public

Internet. Effectively, a corporation uses a wide-area network as

a single large local area network. A company no longer needs

to lease its own lines for wide-area communication but can

securely use the public networks. This kind of interconnection

is known as a virtual private network (VPN).

PCMCIA - The PCMCIA (Personal Computer Memory Card

International Association) is an industry group organized in 1989

to promote standards for a credit card-size memory or I/O device

that would fit into a personal computer, usually a notebook or

laptop computer.

Print Server - A hardware device that enables a printer to be

located anywhere in the network.

RIP (Routing Information Protocol) – A simple routing protocol

that is part of the TCP/IP protocol suite. It determines a route

based on the smallest hop count between source and

up to six wires. The RJ-11 is the common connector used to

plug a telephone into a wall.

Static IP Address - A permanent IP address that is assigned to

a node in a TCP/IP network.

SPI (Stateful Packet Inspection) – Maintains a log of sessions

and requests for each application and determines if the

conditions between the client and the application are “normal”.

If a request appears unrelated to the current application session,

the request is denied.

RJ-45 - A connector similar to a telephone connector that holds

up to eight wires, used for connecting Ethernet devices.

Router - Protocol-dependent device that connects sub networks

together. Routers are useful in breaking down a very large

network into smaller sub networks; they introduce longer delays

and typically have much lower throughput rates than bridges.

Static Routing - Forwarding data in a network via a fixed path.

Static routing cannot adjust to changing line conditions as can

dynamic routing.

Routing Table – Is a user defined list of steps stating how to

process various incoming traffic.

TCP (Transmission Control Protocol) – A method (protocol) used

along with the Internet Protocol (IP) to send data in the form of

message units between computers over the Internet. While IP

takes care of handling the actual delivery of the data, TCP keeps

track of the individual units of data (called packets) that a

message is divided into for efficient routing through the Internet.

instructions that performs a particular task is called a “program.”

The two major categories of software are “system software” and

“application software.” System software is made up of control

programs such as the operating system and database

management system (DBMS). Application software is any

program that processes data for the user.

A common

misconception is that software is data. It is not, software tells

the hardware how to process the data.

means receive.

Throughput - The amount of data moved successfully from one

place to another in a given time period.

URL (Uniform Resource Locator) – The address that defines the

route to a file on the Web or any other Internet facility. URLs are

typed into the browser to access Web pages, and URLs are

embedded within the pages themselves to provide the hypertext

links to other pages.

Topology - A network’s topology is a logical characterization of

how the devices on the network are connected and the distances

between them. The most common network devices include

hubs, switches, routers, and gateways.

Most large networks contain several levels of interconnection,

the most important of which include edge connections,

backbone connections, and wide-area connections.

VLAN (Virtual LAN) – A logical association that allows users to

communicate as if they were physically connected to a single

LAN, independent of the actual physical configuration of the

network.
