CHAPTER 15

Static Route

15.1 Overview

This chapter shows you how to configure static routes for your NBG4115.
The NBG4115 usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the NBG4115 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 NBG4115’s
LAN interface. The NBG4115 routes most traffic from A to the Internet through
the NBG4115’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.
