Static Route Screens
This chapter shows you how to configure static routes for your NBG420N.
16.1 Static Route Overview
The NBG420N usually uses the default gateway to route outbound traffic from computers on
the LAN to the Internet. To have the NBG420N 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 NBG420N’s LAN
interface. The NBG420N routes most traffic from A to the Internet through the NBG420N’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.
