Routing
You can use the software application 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.
7.1
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 iPBX30 uses to make these decisions.
7.1.1 Do 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 iPBX30 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 iPBX30. 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 section 3.2.)
• On the iPBX30
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 7.3.2.)
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.
