Multiple WAN - Allows for multiple internet connections to be configured (WANs can also be VLAN interfaces).

The Multiple WAN Feature allows the administrator to configure more than four WANs in the Network Interfaces section for routing. It also supports up to four WANs for WAN Failover and Load Balancing (LB). All four WANs can be probed using the SNWL Global Responder host.

This allows up to 4 ethernet presented links i.e. ADSL, SDSL, Leased Lines etc. to be connected to increase bandwidth and resilience.

All new Gen5 SonicWALL firewalls now support up to four WAN interfaces using the latest SonicOS Enhanced 5.5 firmware available as standard on the TZ 100, TZ 200, TZ 210, NSA 240, NSA 2400, NSA 2400MX, NSA 3500, NSA 4500, NSA 5000, NSA E5500, NSA E6500, NSA E7500 & NSA E8500.
