Configuring IP Routes

You can use Configuration Manager to define specific routes for your Internet and network data.
This chapter provides instructions for creating routes.
Most users do not need to define IP routes. On a typical small home or office LAN, the existing
routes that set up the default gateways for your LAN computers and for the ATU-R130 provide the
most appropriate path for all your Internet traffic.
? On your LAN computers, a default gateway directs all Internet traffic to the LAN port on
the ATU-R130. Your LAN computers know their default gateway either because you
assigned it to them when you modified their TCP/IP properties, or because you
configured them to receive the information dynamically from a server whenever they
access the Internet.
? On the ATU-R130 itself, a default gateway is defined to direct all outbound Internet traffic
to a router at your ISP. This default gateway is assigned automatically by your ISP
whenever the device negotiates an Internet connection.
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.{ XE "IP

Viewing the IP Routing Table

All IP-enabled computers and routers maintain a table of IP addresses that are commonly
accessed by their users. For each of these destination IP addresses, the table lists the IP address
of the first hop the data should take. This table is known as the device' s routing table.
To view the ATU-R130' s routing table, click the Routing tab. The IP Route Table displays, as
shown in Figure 32.
Figure 31. IP Route Table Page{ XE "IP Route Table page" }{ XE "Pages:IP Route Table" }
The IP Route{ XE "IP address:in device's routing table" } Table displays a row for each existing
route. These include routes that were predefined on the device, routes you may have added, and
routes that the device has identified automatically through communication with other devices.
The routing table should reflect a default gateway, which directs outbound Internet traffic to your
ISP. This default gateway is shown in the row containing destination address 0.0.0.0.
The following table defines the fields in the IP Routing Table.
