Static Route
12.1
Overview
The ZyXEL Device usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the ZyXEL Device send data to
devices not reachable through the default gateway, use static routes.
For example, the next figure shows a computer (
A
) connected to the ZyXEL
Device’s LAN interface. The ZyXEL Device routes most traffic from
A
to the
Internet through the ZyXEL Device’s default gateway (
R1
). You create one static
route to connect to services offered by your ISP behind router
R2
. You create
another static route to communicate with a separate network behind a router
R3
connected to the LAN.
