Can't host Warcraft 3 TFT servers over COMODO firewall

I have a problem hosting with Warcraft 3 The Frozen Throne and Ghost One under COMODO Firewall.Nobody can join my server but if I disable the COMODO Firewall then the others can join. I talked with 3 or 4 operators from LiveSupport and they tried to help me, they even remote controlled my PC to try and solve this but they couldn’t. They added the programs to the firewall like being Trusted Applications and some other things but it didn’t work.
My PC’s OS is Windows 7 Ultimate 64bit,COMODO version is 4.0.138377.779 and the firewall from Windows is Off. If there is something else that you need to know about my PC just tell me.
