I have been using ESS firewall for several months, and it works fine. but now it blocks all program except the known ones with rules. I swtiched across different filtering modes and rebooted many times but that doesn't help. This happened suddenly. I have now idea what caused this. All i know now is that if i deactivate a master rule named "Forbidden", ESS will prompt for permission again when a new application is trying to connect to the internet. I have never noticed this "Forbidden" rule before and i dont know since when it is there and activated. Is it a default a rule that i shouldn't disable? or does my ESS firewall have any problem ?
