WAN Screens
This chapter describes how to configure WAN settings. 
"
WAN 2 refers to the 3G card on the supported ZyXEL Device.
6.1  WAN Overview
• Use the WAN General screen to configure operation mode, route priority and connection 
test for the ZyXEL Device. 
• Use the WAN 1 screen to configure the WAN1 interface for Internet access on the ZyXEL 
Device.
• Use the 3G (WAN 2) screen to configure the WAN2 interface for Internet access on the 
ZyXEL Device.
• Use the Traffic Redirect screen to configure an alternative gateway.
6.2  Multiple WAN 
You can use a second connection as a backup to enhance network reliability. 
The ZyXEL Device has two WAN ports. You can optionally activate the internal 3G card to 
use the second 3G WAN interface. You can connect one interface to one ISP (or network) and 
connect the other to a second ISP (or network). 
The ZyXEL Device's NAT feature allows you to configure sets of rules for one WAN interface 
and separate sets of rules for the other WAN interface. Refer to 
details.
You can select through which WAN interface you want to send out traffic from UPnP-enabled 
applications (see 
). 
The ZyXEL Device's DDNS lets you select which WAN interface you want to use for each 
individual domain name. The DDNS high availability feature lets you have the ZyXEL Device 
use the other WAN interface for a domain name if the configured WAN interface's connection 
goes down. See
