XG User Portal from WAN

Hello Guys,

i wan´t to connect to Userportal from WAN, i allowed the connection from WAN in the XG Settings.

I have a FritzBox(exposed Host) -> XG (dyndns + Userportal Port 443) -> LAN

From Lan i can connect to UserPortal but from WAN not, also a restart does not help. Firefox say the Server is using Old Security Mechanism SSL/TLS1.0 (can i change it in the XG ?)

I also setup a new FritzBox (Userportal Fritz Port 60000 Works)

If you need further Information i´ll reply soon.

regards
