Configuring Secondary WAN Interface
Perform the following steps to configure WAN Failover and
Load Balancing on the SonicWALL security appliance:
1. On Network > Interfaces page, configure the chosen port
to be in WAN zone, and enter the correct address settings
provided by the Secondary ISP.
Note:
In the example Multiple ISP / WAN Failover and Load
Balancing section, on page 53, the SonicWALL security
appliance is acquiring its secondary WAN address
dynamically from ISP #2, using DHCP. Any interface
added to the WAN zone by default creates a NAT policy
allowing internal LAN subnets to enforce NAT on this
Secondary WAN interface.
Activating and Configuring WAN Failover
To configure the SonicWALL for WAN failover and load
balancing, follow the steps below:
1. On Network > WAN Failover & LB page, select Enable
Load Balancing.
2. If there are multiple possible secondary WAN interfaces,
select an interface from the Secondary WAN Ethernet
Interface.
