3.2.7 WAN Policy  
The WAN policy for multi-homing can be setup here. You can setup policy for each WAN  
separately. The router will balance the loading between all active WAN ports according to the  
Send/Receive rate of the WAN ports. You can setup an IP for the router to detect if the WAN line  
is connected. If the router fails to ping the IP, it would recognize the WAN line as not connected,  
and will stop directing the Internet traffic to this WAN port. The traffic will be redirected to the  
other active WAN port. The Intranet users will not become aware of this change and keep surfing  
the Internet smoothly. You also can setup a WAN port as a backup WAN port. Backup WAN port  
would not be activated when the router start up. When the other active WAN port fails to connect  
to the Internet, the backup WAN port will be activated and take over all the traffic.  
Parameter

on start up. But when other enabled WAN ports fail, the backup  
WAN port will be activated and take over all the traffic.  
3.2.8 QoS  
The QoS can let you classify Internet application traffic by source/destination IP, MAC address  
and port number. You can assign priority for each type of application and reserve bandwidth for it.  
The packets of applications with higher priority will always go first. Lower priority applications will  
get bandwidth after higher priority applications get enough bandwidth. This can let you have a  
better experience in using critical real time services like Internet phone, video conference etc.  
All the applications not specified by you are classified as rule name Others. The rule with  
smaller priority number has higher priority; the rule with larger priority number has lower priority.  
You can adjust the priority of the rules by moving them up or down.  
If the total assigned bandwidth of higher priority applications is larger than the  
maximum bandwidth provided by the WAN port, the other applications will not get  
any bandwidth.  
?Note:

Glossary  
Default Gateway (Router): Every non-router IP device needs to configure a default gateways IP  
address. When the device sends out an IP packet, if the destination is not on the same network,  
the device has to send the packet to its default gateway, which will then send it out towards the  
destination.  
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives every computer  
on your home network an IP address.  
DNS Server IP Address: DNS stands for Domain Name System, which allows Internet servers to  
have a domain name (such as www.Broadbandrouter.com) and one or more IP addresses (such  
as 192.34.45.8). A DNS server keeps a database of Internet servers and their respective domain  
names and IP addresses, so that when a domain name is requested (as in typing  
"www.planet.com.tw" into your Internet browser), the user is sent to the proper IP address. The  
DNS server IP address used by the computers on your home network is the location of the DNS  
server your ISP has assigned to you.  
DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone  
lines to transmit data at high speeds.  
Ethernet: A standard for computer networks. Ethernet networks are connected by special cables  
and hubs, and move data around at up to 10/100 million bits per second (Mbps).  
Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet for a pre-  
configured amount of time, the connection will automatically be disconnected.  
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP address consists  
of a series of four numbers separated by periods, which identifies a single, unique Internet  
computer host in an IP network. Example: 192.168.0.1. It consists of 2 portions: the IP network  
address, and the host identifier.  
The IP address is a 32-bit binary pattern, which can be represented as four cascaded decimal  
numbers separated by .: aaa.aaa.aaa.aaa, where each aaacan be anything from 000 to 255,  
or as four cascaded binary numbers separated by .: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb,  
where each bcan either be 0 or 1.  
A network mask is also a 32-bit binary pattern, and consists of consecutive leading  
1s followed by consecutive trailing 0s, such as  
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be  
described simply as xnumber of leading 1s.  
When both are represented side by side in their binary forms, all bits in the IP address that  
correspond to 1s in the network mask become part of the IP network address, and the remaining  
bits correspond to the host ID.  
For example, if the IP address for a device is, in its binary form,  
11011001.10110000.10010000.00000111, and if its network mask is,  
11111111.11111111.11110000.00000000  
It means the devices network address is  
11011001.10110000.10010000.00000000, and its host ID is,  
00000000.00000000.00000000.00000111. This is a convenient and efficient method for routers  
to route IP packets to their destination.

ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP address for  
the Internet router located at the ISP's office.  
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet for  
individuals and other businesses or organizations.  
LAN: Local Area Network. A LAN is a group of computers and devices connected together in a  
relatively small area (such as a house or an office). Your home network is considered a LAN.  
MAC Address: MAC stands for Media Access Control. A MAC address is the hardware address  
of a device connected to a network. The MAC address is a unique identifier for a device with an  
Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds to the  
Manufacturer ID (unique for each manufacturer), plus 3 bytes that are often used as the products  
serial number.  
NAT: Network Address Translation. This process allows all of the computers on your home  
network to use one IP address. Using XRT-Ds NAT capability, you can access the Internet from  
any computer on your home network without having to purchase more IP addresses from your  
ISP.  
Port: Network Clients (LAN PC) uses port numbers to distinguish one network  
application/protocol over another. Below is a list of common applications and protocol/port  
numbers:

PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data  
transmission method originally created for dial-up connections; PPPoE is for Ethernet  
connections. PPPoE relies on two widely accepted standards, Ethernet and the Point-to-Point  
Protocol. It is a communications protocol for transmitting information over Ethernet between  
different manufacturers  
Protocol: A protocol is a set of rules for interaction agreed upon between multiple parties so that  
when they interface with each other based on such a protocol, the interpretation of their behavior  
is well defined and can be made objectively, without confusion or misunderstanding.  
Router: A router is an intelligent network device that forwards packets between different  
networks based on network layer address information such as IP addresses.

Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided by your  
ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used to  
create IP address numbers used only within a particular network (as opposed to valid IP address  
numbers recognized by the Internet, which must be assigned by InterNIC).  
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram  
Protocol (UDP). TCP/IP is the standard protocol for data transmission over the Internet. Both TCP  
and UDP are transport layer protocol. TCP performs proper error detection and error recovery,  
and thus is reliable. UDP on the other hand is not reliable. They both run on top of the IP (Internet  
Protocol), a network layer protocol.  
WAN: Wide Area Network. A network that connects computers located in geographically  
separate areas (e.g. different buildings, cities, countries). The Internet is a wide area network.  
Web-based management Graphical User Interface (GUI): Many devices support a graphical  
user interface that is based on the web browser. This means the user can use the familiar  
Netscape or Microsoft Internet Explorer to Control/configure or monitor the device being managed.
