Configure Virtual Private Network (VPN) Passthrough on RV320 and RV325 VPN Router Series

Objective

VPN Passthrough is a feature which is used to allow VPN traffic generated from VPN clients connected to this router to pass through the router. Generally, every router supports Network Address Translation (NAT) in order to conserve IP addresses when you want to support several clients with the same Internet connection. However, PPTP and IPSec VPN do not support NAT. The VPN passthrough allows PPTP and IPSec VPN only to pass through to the Internet, which is initiated from a VPN client, and then reach the remote VPN gateway. This feature is commonly found on home routers that support NAT.

The objective of this document is to explain how to enable VPN Passthrough on RV32x VPN Router Series.

Step 3. (Optional) To allow PPTP tunnels to pass through the router, check the Enable PPTP PassThrough check box. This option should be enabled when the router lies between two end points of a PPTP VPN tunnel.

Step 4. (Optional) To allow L2TP tunnels to pass through the router, check the Enable L2TP PassThrough check box. This option should be enabled when the router lies between two end points of a L2TP VPN tunnel.
