7 Configuring Static 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 static routes. Note that most users do not need to define static routes.

7.1Overview 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 RX3141 uses to make these decisions.

7.1.1Do I need to define static routes?

Most users do not need to define static routes. On a typical small home or office network, the existing routes that set up the default gateways for your LAN computers and for the RX3141 provide the most appropriate path for all your Internet traffic.

fOn your LAN computers, a default gateway directs all Internet traffic to the LAN port on the RX3141. 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. (Each of these processes is described in the Quick Start Guide instructions, Part 2.)

fOn the RX3141 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 7.2.2 Adding Static Routes.)

You may need to define static 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.
