Some wouldn't even call it a firewal. But i see there is some demand. Shown by quite a few post. Littele Snitch I had open another topic asking this 2 weeks ago. But it was a bit off topic so i decide to start this one. I think after searching for nearly 2 month i finally find my perfect Firewall. Jammer. BUT it doesn't work on XP!! See? A lot of people are already behind Firewall / Routers. And Most of them only need a Simple Application control. Telling them " xxxxx.exe is trying to acces internet." Allow of deny. Simple!. But most firewall comes in All in one soloution and the market is lacking these simple things. Zonealarm Free 4.5 was very close but it was a resource Hog ( ~15 Mb Ram? ) Compare to WHat i heard 2Mb for Jammer. I really Hope Agnitum could pick up and resurrect Jammer. ( Although in reality Jammer never died and it is still being sold >_< ) P.S - Just out of a matter of interest, How is interested in such a firewall.?
