need some help with configuration

[Davood]

Simple version:
i updated my db and codebase to current code. now people can't login to my server

Explanation:
If I connect from inside the lan pretending im going to the internet. I can
1. connect to char select
2. connect to zone and play around in game

If i connect purely from outside the lan I can
1. connect to char select
2. free ride back to login screen, do not pass go.
3. server doesn't tell me aynthing useful, it thinks everything is good.


the catch:
just before i updated my db and codebase, people were abel to connect to my server. i have not changed my configs on router, and my internal and external ips are the same

i'm out of research options, i need expert advice please!
