9.1 Overview
This chapter discusses the ZyWALL's WAN screens. Use these screens to configure your
ZyWALL for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks (such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other
locations.
The ZyWALL has a multiple WAN feature which enables you to connect up to two ISPs (or
networks). The ZyWALL 5 also supports a 3G WAN connection. You can configure the
distribution of traffic on the WAN connections using the load balancing settings.
You can have either a wired WAN connection with a 3G (WAN) connection or two wired
WAN connections as shown in the following figures.
