CHAPTER 13
Static Route
13.1 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.

13.1.1 What You Can Do in the Static Route Screens
Use the Static Route screens (Section 13.2 on page 212) to view and configure IP static routes
on the ZyXEL Device.
