VPN Gateway-to-Gateway: Dual Gateway WAN Ports for Load Balancing
In the case of the dual WAN ports on the gateway VPN firewall
gateway WAN ports at one end can be programmed in advance to initiate the VPN tunnel with the
appropriate gateway WAN port at the other end as necessary to manage the loads of the gateway
WAN ports because the IP addresses of the WAN ports are known in advance.
Figure C-16
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 Telecommuter (Client-to-Gateway Through a NAT Router)

Note: The telecommuter case presumes the home office has a dynamic IP address and
NAT router.
The following situations exemplify the requirements for a remote PC client connected to the
Internet with a dynamic IP address through a NAT router to establish a VPN tunnel with a gateway
VPN firewall at the company office:
• Single gateway WAN port
• Redundant dual gateway WAN ports for increased reliability (before and after rollover)
• Dual gateway WAN ports used for load balancing
