At work we have a Mac Mini server with VPN setup for L2TP and PPTP access to the files stored on it.

We have just installed a new router (Draytek Vigor2860) and now can't access the server when working remotely, from home etc...

We have a static IP address for the server (10.0.XX.X) and the following open ports on the router: 1723, 1701, 47, and 500. These ports are also redirected to the server's static IP address. There's also a preshared key which is used in the VPN connection on my machine.

Despite this anytime I try to connect via VPN I'm still getting error 800 messages, does anyone know where I'm going wrong on this?

Many thanks in advance for any help you can provide.

Disable the Vigor router's own VPN service, as otherwise it may intercept the incoming connections (or let the Vigor handle the VPN itself).

I have already unchecked the options to enable PPTP, IPSec, L2TP and SSL VPN on the router under Remote Access Controll Setup but it still gives me Error 800 messages. Any other ideas?
