Port forwarding

[Phenomenon]

I know this isn't mangos related, but I didn't know where else to turn to. I'm trying to port forward so that me and my friend can mess around on my server, but I can't seem to get it right. I've done research, tried tons of stuff, used port forwarding applications, etc. Nothing. Is. Working.

Everything is allowed through my firewall, anti-viruses aren't an issue, I'm on Windows 7, have a dynamic IP (I change everything as needed though) and have a DLink DIR-615.

Like I've said I've done tons of research, so what I'm starting to think is that I need help on MaNGOS port forwarding specifically since all the general help doesn't seem to be helping me.

Any help or even a point in the right direction is extremely appreciated, thanks
