Hi all
I know this is a site mainly used for tf2 but I need some help in killing floor. I want to be able to setup my own server but I have absolutely no idea on how to open a port, and unless I do no one can join my game. Ive tried googlein it but I still don't get it. the OS i use is windows 7 home prem 32 bit. If posible please could you use the most basic language posible as I have absolutely no idea of what to do.

Apparantly i need to open theses ports.

7707 UDP/IP (Game Port)
7708 UDP/IP (Query Port)
7717 UDP/IP (GameSpy Query Port)
28852 TCP/IP and UDP (Allows your Server to Connect to the Master Server Browser)
8075 TCP/IP (Port set via ListenPort that your WebAdmin will run on)
20560 UDP/IP (Steam Port)

If anyone can help me it would be much appricated.
