Wireless-N Gigabit Gaming Router The SECURITY Tab - VPN PASSTHROUGH The VPN PASSTHROUGH screen allows you to allow VPN tunnels usingPPPoE, IPSec, PPTP or L2TP protocols to pass through the Router. VPN Passthrough PPPoE Passthrough. PPPoe (Point-to-Point Protocol over Ethernet) allows a PPP session to be initiated on a simple bridging Ethernet connected client. To allow PPPoE Passthrough, click the Enable button. To disable PPPoE Passthrough, click the Disable button. IPSec Passthrough. IPSec (Internet Protocol Security) is a suite of protocols used to implement secure exchange of packets at the IP layer. To allow IPSec Passthrough, click the Enable button. To disable IPSec Passthrough, click the Disable button. PPTP Passthrough. PPTP (Point-to-Point Tunneling Protocol) allows the Point-to-Point (PPP) to be tunneled through an IP network. To allow PPTP Passthrough, click the Enable button. To disable PPTP Passthrough, click the Disable button. L2TP Passthrough. L2TP (Layer 2 Tunneling Protocol) is the method used to enable Point-to-Point sessions via the Internet on the Layer 2 level.
