Vpn Gateway-To-Gateway - NETGEAR FVX538v2 - ProSafe VPN Firewall Dual WAN Reference Manual

ProSafe VPN Firewall 200 FVX538 Reference Manual
The IP addresses of the gateway WAN ports can be either fixed or dynamic. If an IP address is
dynamic, a fully-qualified domain name must be used. If an IP address is fixed, a fully-qualified
domain name is optional.

VPN Gateway-to-Gateway

The following situations exemplify the requirements for a gateway VPN firewall to establish a
VPN tunnel with another gateway VPN firewall:
• Single gateway WAN ports
• Redundant dual gateway WAN ports for increased reliability (before and after rollover)
• Dual gateway WAN ports used for load balancing
VPN Gateway-to-Gateway: Single Gateway WAN Ports (Reference Case)
In the case of single WAN ports on the gateway VPN firewalls, either gateway WAN port can
initiate the VPN tunnel with the other gateway WAN port because the IP addresses are known in
advance.

The IP address of the gateway WAN ports can be either fixed or dynamic. If an IP address is
