After my ZoneAlarm firewall busted up, I was searching for another good firewall to protect my system. Frankly, I had no hopes of getting any though. But I chanced upon this piece of software called Enigma Firewall. Boy, it does its job!!!! It is far more explicit than Zone Alarm and allows you to configure a good set of filter rules. If any one of you have used it, pls let me know your experience.
