THIS IS NOT FOR HACKING OR WHATEVER MY THREAD WAS CLOSED FOR. THIS IS LEGAL AND IS USED TO UNBLOCK iChat. IF IT WAS NOT LEGAL ISA WOULD NOT BE ON THE MICROSOFT SITE. guys PC's have a ISA firewall. I am a student at a collage but and they block everything i need to get though and open about 6 ports. How would i be able to do this because i am quite desperate Is there anything that i need to download? could anybody help me? THANK YOU.
