VPN Telecommuter: Dual-Gateway WAN Ports for Load Balancing

In a gateway configuration with dual WAN ports that function in load balancing mode, the

remote computer client initiates the VPN tunnel with the appropriate gateway WAN port (that

is, port WAN1 or WAN2 as necessary to balance the loads of the two gateway WAN ports)

because the IP address of the remote NAT router is not known in advance. The selected

gateway WAN port needs to act as the responder.

Figure 277.

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

is dynamic, you need to use an FQDN. If an IP address is fixed, an FQDN is optional.
