INTRODUCTION
With the explosive growth of the Internet, accessing information and
services at any time, day or night, has become a standard requirement for
most people. The era of the standalone PC is waning. Networking
technology is moving out of the exclusive domain of corporations and
into homes with at least two computers.
This integrated access device combines Internet gateway functions with
wireless LAN and Fast Ethernet switch. Designed for the business and
home, it saves you the cost of installing a separate modem and ISP line
for each computer, while providing ready connection for the users, with or
without network cables.
Broadband network access is also gaining ground. However, allowing
more than two computers to access the Internet at the same time means
higher costs. Thus, there is a need to share one legal IP address over a
single Internet connection to link each computer with the Internet.
The scarcity of IP addresses and using a shared Internet connection
through an Internet sharing device can solve high network access costs.
All linked computers can make full use of broadband capabilities over
such a device.
This device not only comes equipped with a wide range of features, but
also comes installed and configured right out of the box. This device
supports a simple local area network and Internet access sharing, offering
great cost savings.
The local area network connects home computers while also allowing any
of the computers to access the Internet, share resources, or play online
games—the basis of the family computing lifestyle.

Some applications require multiple connections, such as Internet gaming,
video conferencing, Internet telephony and others. These applications
cannot work when Network Address Translation (NAT) is enabled. When
users send this type of request to your network via the Internet, the Router
will forward those requests to the appropriate PC. If you need to run
applications that require multiple connections, specify the port normally
associated with an application in the "Trigger Port" field, select the
protocol type as TCP or UDP, then enter the public ports associated with
the trigger port to open them for inbound traffic.

TCP (Transmission Control Protocol) - A communications method
(protocol) used along with the Internet Protocol (Internet Protocol) 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 takes care of keeping track of the individual units of data
(called packets) that a message is divided into for efficient routing
through the Internet.
·
UDP (User Datagram Protocol) - A communications method
(protocol) that offers a limited amount of service when messages are
exchanged between computers in a network that uses the Internet
Protocol (IP). UDP is an alternative to TCP and, together with IP, is
sometimes referred to as UDP/IP. Like the Transmission Control
Protocol, UDP uses the Internet Protocol to actually send a data unit
(called a datagram) from one computer to another. Unlike TCP,
however, UDP does not provide the service of dividing a message
into packets and reassembling it at the other end. Specifically, UDP
doesn't provide sequencing of the packets that the data arrives in.
This means that the application program that uses UDP must be able
to make sure that the entire message has arrived and is in the right
order. Network applications that want to save processing time
because they have very small data units to exchange (and therefore
very little message reassembling to do) may prefer UDP to TCP.

2-5-2 Virtual Server
Configure the Broadband Router as a virtual server to allow the Router to
watch outgoing data for specific port numbers. The IP address of the
computer that sends the matching data is remembered by the Router, so
that when the requested data returns through the Router, the data is pulled
back to the proper computer by way of IP address and port mapping rules.
Depending on the requested service (TCP/UDP port number), the
Broadband Router redirects the external service request to the appropriate
server.

2-6 Firewall
The Broadband Router provides extensive firewall protection by
restricting connection parameters to limit the risk of hacker attacks, and
defending against a wide array of common hacker attacks.
The Broadband Router provides packet filtering rules by restricting
service ports, IP address, or MAC address. However, for applications that
require unrestricted access to the Internet, configure
client/server as a demilitarized zone (DMZ).

2-6-1 Block WAN Ping
When the "Discard PING from WAN side" is activated, the Broadband
Router will not to respond to ping commands originating from the WAN.
Pinging public WAN IP addresses is a common method used by hackers
to test whether the WAN IP address is valid and supports a network.

2-6-2 Client Filtering
You can filter Internet access for local clients based on IP addresses,
application types, (i.e., HTTP port), and the time of day.
For example, the following picture shows that clients in the address range
192.168.1.50-99 are permanently restricted from using FTP (Port 21),
while clients in the address range 192.168.1.110-119 are blocked from
browsing the Internet (port 80) from Monday to Friday and from 0:00AM
to 11:00 PM.
Example:
2-6-3 MAC Control
You can block certain client PCs from accessing the Internet based on
their MAC address.
2-6-4 DMZ (Demilitarized Zone)
If a local client PC cannot run an Internet application properly from
behind the NAT firewall, open the client up to unrestricted two-way
Internet access by defining a virtual DMZ Host.
