I have a Asus RT-N16 router with Tomato 1.28 installed, and I may say, this makes life great!
No issues with anything up to now…
I have a VPN server hosted locally on my server box, up to now I have been exclusively using PPTP for connection to the VPN server.
I am trying to enable L2TP as a connection option for the VPN in addition to PPTP, I have enabled it, and connections to the server locally work fine.
Under 'Port Forwarding' I forwarded the ports "UDP 500,4500" to my VPN server. But I am unable to connect over the internet…
I think I am missing something, but I am unsure what it may be. Like I said, connections to the VPN using L2TP internally/locally using the Local IP address are working correctly. The PPTP over the internet is working correctly also, I forwarded the ports in the same manner with no issues some time ago.
Thanks in advanced for any input.
