Jetico PF seems to have a problem with apps that either auto startup or hook to keyboard events. Not sure yet which is the problem. But it results in unexpected processing of the Application Table. I added Jetico PF to a fresh install of XP SP2 with NOD32. After tuning the Optimal Policy rules to ensure NOD32 can autoupdate, I proceed to try ping, telnet, nslookup and ftp from a Command Prompt window. When I ping my DSL router, Jetico popups appear for SynTPLpr.exe (Synaptics Touchpad Driver Helper), Setup.exe (Audio Volume Status app for my notebook), cmd.exe, then finally ping.exe. If I deny network access to SynTPLpr.exe or Setup.exe, then Jetico doesn't even prompt for the rest. And ping.exe will fail with an error. Next, I try to telnet to the web admin port of my DSL router. Again, these require the SynTPLpr.exe, Setup.exe and cmd.exe above to be ticked as 'accept'. Else, no popup prompt for telnet.exe . And telnet.exe will fail with error. Next, I try nslookup. Same as above, but no popup for sending datagram (UDP) appears. Lastly, I try ftp to my DSL router. A popup for lxkey.exe (EzButtonPro app for my notebook) appears, then ftp.exe . Perhaps 'network access' is required for random hotkey apps, for the networking commands to function. In a separate clone partition, I had blocked 'network access' to many of these keypanel apps, thinking they had no business attempting it. But then Internet Explorer silently failed to open any web page, with no popup appearing from the Ask User rule. I will continue to evaluate Jetico PF a bit more. However, I am concerned how much more is broken in the Application filter, and if anything is broken elsewhere.
