I've been trying to block IRC in Vista with Zone Alarm.
I went to expert rules, and made a Protocol Group called "IRC ports" that specifies TCP destination ports 194, 6660-9, 6679, 6697 and 531.
When I apply an expert rule that the IRC client should be blocked against this Protocol Group (in program control>program>options>expert rules), it blocks IRC.
But when I made an expert rule that the entire computer should be blocked against this protocol group (in firewall>expert) , nothing happened.
So then I tested an expert rule that blocks TCP port 80. As far as I can tell, this should have crippled the entire internet, but it did nothing.
Is there a reason the expert rules don't work?
Using the latest ZoneAlarm and fully patched Windows Vista.
Thanks for your help,
Operating System:Windows Vista Home Premium
