(edit: sorry I think the version I used was 2.1.5, been a long time ago) I used to use Kerio PFW when running XP. Now running Win7 and have been unable to find a firewall that has the real time logging feature of the old Kerio PFW. The things I miss most are being able to see connectiong real time, data being transferred, whether inbound or outbound, protocol being used, rule being applied. The other thing I miss is the simple alert as to whether or not to allow a program. You could get a real good idea of what is happening to your PC in real time and even if you're not a networking wiz you could figure out any problems simply by watching the real time log. All of the free firewalls I have tried, and I have not tried them all do not allow this user-connection interplay. They mostly do things behind the scenes and you have to guess what they are doing real time. Doesn't really teach you anything, nor show you what is actually happening. Of the many, many free firewalls out there (or even paid if need be) there must be one that has this feature. Also when is some smart guy going to rebuild Kerio 2.1.15 so it works on Win7 and up? That company (cannot recall the name off hand) that supposedly took over Kerio is no good. I tried their so called revised kerio firewall and it blue screened consistently. Anyone?
