3.5.1 VPN pass through
VPN is the abbreviation for Virtual Private Network, which provide a secured
link through public network by encrypting data between local and remote sides.
In order to pass through VPN traffic, router needs to recognize VPN packets
and pass them in transparent way. VPN packets like IP Sec., PPTP and L2TP will
not be affected and passed to the destination for appropriate process as desired.
Example: Select Pass through protocol and fill its local IP.
