This chapter describes how to use the virtual private networking (VPN) features of the VPN 
firewall.

If both of the WAN ports of the VPN firewall are configured, you can enable either Auto-Rollover 
mode for increased system reliability or Load Balancing mode for optimum bandwidth efficiency. 
This WAN mode choice impacts how the VPN features must be configured.

The use of fully qualified domain names in VPN policies is mandatory when the WAN ports are in 
load balancing or rollover mode; and is also required for the VPN tunnels to fail over. FQDN is 
optional when the WAN ports are in load balancing mode if the IP addresses are static but 
mandatory if the WAN IP addresses are dynamic. 

Refer to 

 for more on the IP addressing 

requirements for VPN in the dual WAN modes. For instructions on how to select and configure a 
dynamic DNS service for resolving FQDNs, see
