Hosting problem in Windows 7

Hello guys, Marry Christmas and Happy New Year tomorrow:)

Quickly at the point... In some parts of the year I start missing War3 battle.net i come back for playing. Long time ago I learned to manage opening ports through router or directly from my Internet provider modem. For first time now I mess with that kind of problem and I think it is from the Windows. I opened from 6112 to 6119 for all IPs i use and same... I learned from Google some specific details for Win7 and did it too. Firewall is OFF too... I read the topic about antivirus softwere and so on... no, i'm with AVG... So... is there any logical explaination about this? Seems like everything is fine but I still can't host. I cheked with the PFPortChecker, i found it in the forum... It shows me same... ports blocked... now what? Any suggestions? :(

Thank you and sorry for the disturbing:) Nice time during the holidays and I wish you the best of luck! :)

maybe the IP of your router / pc has changed?
