TL-R600VPN PPTP Tunnel as WAN
I have established unencrypted PPTP VPN tunnel successfully from my TL-R600VPN to a commervial VPN provider PureVPN. I'm trying to treat this PPTP tunnel as WAN and route internet traffic from a certain LAN IP through this tunnel with policy routing but so far unsuccessful. This works fine if I connect PPTP to the same provider through an additional WAN interface, but I prefer to use the VPN tunneling method on top of my existing WAN interface. Is this possible?
From the router diagnostics menu, I can successfully ping internet sites through the VPN tunnel, but any traffic from local PCs cannot reach the internet. If I try to ping to the internet from PC the router respond with Destination Unreachable. I have tried different settings on the working mode (NAT and route), different settings on the remote subnets and multi-nets NAT but still unsuccessful. If I use static routing on specific destination IPs and route it through the tunnel it works, the PC can reach the internet, but policy routing doesn't seem to work.
Amy I missing something? Appreciate any help.
