Routing; Chapter 7 Routing; Overview - Huawei B222s User Manual

7.1 Overview

The LTE Device usually uses the default gateway to route outbound traffic from computers on the
LAN to the Internet. To have the LTE 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 LTE Device's LAN interface.
The LTE Device routes most traffic from A to the Internet through the LTE 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.
