What's the best free firewall-tester around these days? Recommendations, please. I'm looking for one where I won't subsequently get plagued with adverts for a new firewall.
Obviously, the absolute trustworthiness of one tester utility or another is of paramount importance.
Do all firewall-testers require Active-X to be installed?
For reasons I won't go into here, I'm still using a v6.1 ZA Free, and am wondering which ports might not be adequately covered by it.
Operating System:Windows XP Home Edition
Product Name:ZoneAlarm (Free)
