VPN Pass through Scenario
Since VPN traffic is different from that of TCP or
UDP connection, it will be blocked by NAT gateway.
To support the pass through function for the VPN
connections initiating from VPN clients behind NAT
gateway, the gateway must implement some kind
of VPN pass through function for such application.
The gateway supports the pass through function
for IPsec, PPTP, and L2TP connections.
