WAN Screens
This chapter describes how to configure WAN settings.
7.1 WAN Overview
See
for more information on the fields in the WAN screens.
7.2 Multiple WAN
You can use a second connection for load sharing to increase overall network throughput or as
a backup to enhance network reliability.
The ZyWALL has two WAN ports. You can connect one port to one ISP (or network) and
connect the other to a second ISP (or network).
The ZyWALL can balance the load between the two WAN ports (see
).
You can use policy routing to specify the WAN port that specific services go through. An ISP
may give traffic from certain (more expensive) connections priority over the traffic from other
accounts. You could route delay intolerant traffic (like voice over IP calls) through this kind of
connection. Other traffic could be routed through a cheaper broadband Internet connection that
does not provide priority service. If one WAN port's connection goes down, the ZyWALL can
automatically send its traffic through the other WAN port. See
details.
The ZyWALL's NAT feature allows you to configure sets of rules for one WAN port and
separate sets of rules for the other WAN port. Refer to
for details.
You can select through which WAN port you want to send out traffic from UPnP-enabled
applications (see
The ZyWALL'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 ZyWALL use
the other WAN interface for a domain name if the configured WAN interface's connection
goes down. See
When configuring a VPN rule, you have the option of selecting one of the ZyWALL's domain
names in the
My Address
field.
