8. 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.
Note that most users do not need to define routes.
8.1 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 SL6000/SL6300 uses to make these
decisions.
8.1.1 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 SL6000/SL6300 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 SL6000/SL6300. 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 ac-
cess the Internet. (Each of these processes is described in the Quick
Start Guide instructions, Part 2.)
• On the SL6000/SL6300 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. (The process for adding a default route is described
in section 8.3.2 Adding Static Routes.)
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.
