VPN Pass through Scenario

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