Hello, I have a VPN server that is located behind a Balance One and I have forwarded UDP 500, 4500, 1701, AH, and ESP to my VPN server. Nat-t is enabled.
I can’t seem to connect to my VPN server externally. I can connect internally with L2TP and PPTP just fine, I can connect PPTP externally fine, but L2TP does not work externally. I’ve verified my shared keys and everything else.
If I use the built in VPN server, I can connect to the Peplink using L2TP, but that is not great as it is yet another password the user needs to know.
Does anyone have any ideas?
