Sorry if this isn't the right forum, but i was wondering if anyone could help me configure my firewall settings. I want to block a program from allowing IP's from accessing my computer. The program is a virtual world, i want to block ALL IP's, apart from the ones i need to to connect to the program with. This is possible? The thing is, i made a blocking rule, but i can't seem to locate where to add exceptions. I can't just make a rule and define which IP's i wish to block, because i don't know what those IP's are, i only know which ones i want to allow. I hope that's clear enough of an explanation. Appreciate any help.
