Since Kerio 2.x doesnt filter ipv6, sooner or later I have to give it up. I've tried other firewalls like comodo and zonealarm but I'm not satisfied with both of them for their poorer configurability. I like the logic of how kerio works: rule-based, all rule including application rules and network rules on one page can be moved up and down. Is there any firewall as logical as kerio 2.x ? any recommendations?.
