[Stuck at connected / infinite loop / login issues / battle.net]

I have some problem.

I have router, and server have only local IP, but all traffic rout from router to server.

If i set binding to 0.0.0.0 in authserver.conf i can connect only from LAN machines.

If i try set external IP i have error in console:
