7 Configuring Routes
You can use Configuration Manager to define specific routes for your
Internet and network data communication. This chapter describes basic
routing concepts and provides instructions for creating routes.
7.1 Overview of IP Routes
The essential challenge of a router is: when it receives data intended for a
particular destination, which next device should it send that data to? When
you define IP routes, you provide the rules that the router uses to make
these decisions.
7.1.1 Do I need to define IP 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 router 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 router. 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. Refer to 3.2 Part 2 -- Configuring Your Computers for
more details.
• On the router 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. Refer to 7.3.2 Adding a Static Route for more details on
adding a default route.
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.
