Hi to all!. I some time ago changed my computer and reinstalled windows, and i have some issues that i wanted to fix, but i have no idea. I used mac os, but i've set up windows 7 and i think that there are some problems with firewall. I can't use apache channel because it's often busy and some ports are not working with other computers from the network. Perhaps, it is an issue with cisco, but I'm not sure. So what is your opinion?
