I always noticed there was no predefined policy for messengers like Skype, AIM, Pidgin etc… Since these are somewhat insecure programs to use to begin with what would be the best firewall settings? Has anyone created a predefined policy for these or will “outgoing only” suffice?
for only out-going firewall, you can chnage the configuration under the advanced settings.
Set you configuration to Proactive Configuration, this is what you want.
