ProSafe VPN Firewall 200 FVX538 Reference Manual
• Dual gateway WAN ports used for load balancing
VPN Telecommuter: Single Gateway WAN Port (Reference Case)
In the case of the single WAN port on the gateway VPN firewall, the remote PC client at the NAT
router initiates the VPN tunnel because the IP address of the remote NAT router is not known in
advance. The gateway WAN port must act as the responder.
Figure B-17
The IP address of the gateway WAN port can be either fixed or dynamic. If the IP address is
dynamic, a fully-qualified domain name must be used. If the IP address is fixed, a fully-qualified
domain name is optional.
VPN Telecommuter: Dual Gateway WAN Ports for Improved Reliability
In the case of the dual WAN ports on the gateway VPN firewall, the remote PC client initiates the
VPN tunnel with the active gateway WAN port (port WAN1 in this example) because the IP
address of the remote NAT router is not known in advance. The gateway WAN port must act as the
responder.
