Windows 2008 R2 server L2TP endpoint sitting behind USG-100 with a 1:1 NAT rule. Can connect to the L2TP end point from inside the network, but not outside. Have the following allowed in a service group:
ESP
GRE
IKE
NATT
PPTP
PPTP_Tunnel
UDP 1701
PPTP connects from outside with these rules. I have the firewall set to log all allowed connections for the group rule. The only thing I see is 1723 TCP when I connect via PPTP.
Any ideas?
