• Rollover Case for Dual Gateway WAN Ports
Rollover for the dual gateway WAN port case is different from the single gateway WAN port
case when specifying the IP address of the VPN tunnel end point. Only one WAN port is active
at a time and when it rolls over, the IP address of the active WAN port always changes. Hence,
the use of a fully-qualified domain name is always required, even when the IP address of each
WAN port is fixed.
Note: Once the gateway router WAN port rolls over, the VPN tunnel collapses and
must be re-established using the new WAN IP address.

• Load Balancing Case for Dual Gateway WAN Ports
Load balancing for the dual gateway WAN port case is the same as the single gateway WAN
port case when specifying the IP address of the VPN tunnel end point. Each IP address is
either fixed or dynamic based on the ISP: fully-qualified domain names must be used when the
IP address is dynamic and are optional when the IP address is static.
