Routing

The Routing page enables you to define specific route for your Internet and network data.

Most users do not need to define routes. On a typical small home or office LAN, the

existing routes that set up the default gateways for your LAN hosts and for the DSL device

provide the most appropriate path for all your Internet traffic.

On your LAN hosts, a default gateway directs all Internet traffic to the LAN port(s) on the

DSL device. Your LAN hosts know their default gateway either because you assigned it to

them when you modified your TCP/IP properties, or because you configured them to

receive the information dynamically from a server whenever they access the Internet.

On the DSL device itself, a default gateway is defined to direct all outbound Internet traffic

to a route at your ISP. The default gateway is assigned either automatically by your ISP

whenever the device negotiates an Internet access, or manually by user to setup through

the configuration.

You may need to define routes if your home setup includes two or more networks or

subnets, if you connect to two or more ISP services, or if you connect to a remote

corporate LAN.

Fields in this page:

Field

Description

Enable

Check to enable the selected route or route to be added.

Destination

The network IP address of the subnet. The destination can be specified as the IP

address of a subnet or a specific host in the subnet. It can also be specified as all

zeros to indicate that this route should be used for all destinations for which no

other route is defined (this is the route that creates the default gateway).

Subnet Mask

The network mask of the destination subnet. The default gateway uses a mask of

0.0.0.0.

Next Hop

The IP address of the next hop through which traffic will flow towards the

destination subnet.

Metric

Defines the number of hops between network nodes that data packets travel. The

default value is 0, which means that the subnet is directly one hop away on the

local LAN network.

Interface

The WAN interface to which a static routing subnet is to be applied.

Function buttons in this page:

Add Route

Add a user-defined destination route.

4.5.4

Port Mapping

The DSL device provides multiple interface groups. Up to five interface groups are

supported including one default group. The LAN and WAN interfaces could be included.

Traffic coming from one interface of a group can only be flowed to the interfaces in the

same interface group. Thus, the DSL device can isolate traffic from group to group for

some application. By default, all the interfaces (LAN and WAN) belong to the default

group, and the other four groups are all empty. It is possible to assign any interface to any

group but only one group.

Description

Enabled/Disabled
