[HELP][ASCENT] How to make wan server ?

Hi again,
I recently downloaded kameleon repack, and i want to make the server accesible from WAN. I can connect from LAN if i put the LAN IP of my computer, but if i put the WAN IP from the ISP it only shows up "Authenticating" when I try to log in.
I got a Router that is set to Virtual DMZ to my computer so that it forwards everything there, so I dont understand what the crack happens.

So... I got it work from LAN, and i want to make it work from WAN, but it works only till authenticating then freezes.
Please, help would be much appreciated !

Thanks !

why dont u use hamchi?

Bcoz i want to make it connectable from anywhere, i mean public...
