ProSecure Unified Threat Management (UTM) Appliance Reference Manual

VPN Road Warrior (Client-to-Gateway)

The following situations exemplify the requirements for a remote PC client with no firewall to establish a VPN tunnel with a gateway VPN firewall such as an UTM:

Single gateway WAN port

Redundant dual gateway WAN ports for increased reliability (before and after rollover)

Dual gateway WAN ports for load balancing

VPN Road Warrior: Single Gateway WAN Port (Reference Case)

In a single WAN port gateway configuration, the remote PC client initiates the VPN tunnel because the IP address of the remote PC client is not known in advance. The gateway WAN port must act as the responder.

Figure B-9

The IP address of the gateway WAN port can be either fixed or dynamic. If the IP address is dynamic, a FQDN must be used. If the IP address is fixed, a FQDN is optional.

VPN Road Warrior: Dual Gateway WAN Ports for Improved Reliability

In a dual-WAN port auto-rollover gateway configuration, the remote PC client initiates the VPN tunnel with the active WAN port (port WAN1 in Figure B-10 on page B-12) because the IP address of the remote PC client is not known in advance. The gateway WAN port must act as a responder.
