Network Planning for Multiple WAN Ports

ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
Figure 29. Telecommuter example in a single WAN port configuration with NAT
The IP address of the gateway WAN port can be either fixed or dynamic. If the IP address is
dynamic, you must use an FQDN. If the IP address is fixed, an FQDN is optional.
VPN Telecommuter: Dual-Gateway WAN Ports for Improved Reliability
In a gateway configuration with dual WAN ports that function in auto-rollover mode, the
remote computer client initiates the VPN tunnel with the active gateway WAN port (port
WAN1 in the following figure) because the IP address of the remote NAT router is not known
in advance. The gateway WAN port must act as the responder.
Figure 30. Telecommuter example in a dual WAN port configuration with NAT before auto-rollover
The IP addresses of the gateway WAN ports can be either fixed or dynamic, but you must
always use an FQDN because the active WAN port could be either WAN1 or WAN2 (that is,
the IP address of the active WAN port is not known in advance).
After a rollover of the WAN port occurs, the previously inactive gateway WAN port becomes
the active port (port WAN2 in the following figure) and the remote computer must reestablish
the VPN tunnel. The gateway WAN port must act as the responder.
