For years, ZA's free firewall worked beautifully on my WinXP machine.
A few weeks ago, after installing an updated version of ZA's free firewall, I noticed that it was NOT blocking any inbound intrusions even though the program shows "All Systems Active" and "Firewall is up to date."
I am using the defaulted settings for this firewall, including HIGH for the "Internet Zone."
I have since completely removed ZA and did a complete clean install, but still not blocking any inbound intrusions.
