VPN Pass Through

IPSec Pass Through  Internet Protocol Security (IPSec) is a suite of protocols used to implement secure exchange of packets at the IP layer. IPSec Pass Through is enabled by default to allow IPSec tunnels to pass through the Router.

PPTP Pass Through  Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be tunneled through an IP network. PPTP Pass Through is enabled by default.

L2TP Pass Through  Layer 2 Tunneling Protocol is the method used to enable Point-to-Point sessions via the Internet on the Layer 2 level. L2TP Pass Through is enabled by default.

The PPTP VPN tunnels are displayed.

User Name  It shows the name of the PPTP VPN client.

Remote Address  This shows the WAN IP address of the PPTP VPN client.

PPTP IP Address  This shows the PPTP IP address of the PPTP VPN client. When the PPTP VPN client connects to the PPTP server, it is assigned a PPTP IP address by the PPTP server, which has a pool of pre-configured IP addresses available. (With its PPTP IP address, the PPTP VPN client acts like it belongs to the LAN of the PPTP server.)
