I had my SME Sever 5 setup, and configured PPTP VPN. I was successful to make VPN connection in my LAN, but no success through WAN. When i try to make VPN connection through WAN to my server, i was first get connected and disconnected immidately.
I was able to ping my server and access my web site through WAN. I am using broadband as my internet connection for the server. I had already allow port 1723 and 760 for PPTP connection.
Does anyone know what is my problem? Many thanks.
