Multiple ISP / WAN Failover and Load Balancing
X1 WAN
In this scenario, the SonicWALL TZ 210 is
configured in NAT/Route mode to operate
as a network gateway with multiple
Internet Service Providers (ISPs) to allow
load balancing and/or failover. Typical
zone assignments for this scenario are as
follows:
Local Network (LAN)
- wired local client
computers and servers
Multiple Internet (WAN)
- two Internet
service providers connected through X1
and a second open port (X3 in this case)
DMZ
- (optional) wired resources
available to public Internet such as Web
servers and Mail servers
Wireless (WLAN)*
- wireless local client
computers and devices
*For the TZ 210 wired appliance, wireless is
achieved by adding a SonicWALL SonicPoint
appliance to any free interface (X4-X5) and
zoning that interface as WLAN.
