•Use the Dial Backup screen to configure the backup WAN dial-up connection.

7.2Multiple 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 Section 7.3 on page 127).

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 Chapter 24 on page 392 for 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 Chapter 22 on page 370 for details.
