What do I need to enable in virgin media superhub to properly forward L2TP/IPSec to my VPN server?
Right now, I have PPTP vpn server that I can connect to using my pubic IP address just fine. All I had to do was to enable PPTP Pass-Through in superhub and forward TCP port 1723.
I am trying to upgrade to L2TP/IPSec but I hit the wall. I have forwarded UDP ports 500, 1701, and 4500, and enabled IPSec Pass-Through, but I cannot connect using my public IP address. I can connect just fine within my LAN, therefore it is superhub's fault, not client's or server's.
