– 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.
