From the ones I have seen, pretty much ALL software firewalls work this way.
I suppose it just makes sense.

Incidentally, I tried Kerio, but decide to ditch it after I noticed a few 
- firstly I didnt like the way it allowed remote access to its 
settings/logs, nor the way it used this same system to log the local user 
into it's settings/logs console.
- it seemed to be the above system that was frequently failing when I logged 
in, giving errors, and not working as it should, if at all.

That said, it was always WinGate (Kerios previous incarnation) that I used 
back in the win 3.11 days.

It's entirely possible that I had some disabled services causing this 
problem (i'm pretty sure I had telnet services enabled at the time - but 
normally do not). But it was only working intermittently....so ZIIIP: out 
comes the recent ghost image CD.

Around the same time i tried out ZoneAlarm, and despite it seeming mostly 
ok, i did find it to be a little too idiot proofed for me to feel 
comfortable about it. I can't remember exactly, but i think it related to 
the lack of information it logged, and the limited variety of access/denial 

I also tried TermiNet firewall demo, and VirusMD firewall.... IIRC both 
seemed pitifully primitive, and probably not all that effective.... but it 
was a fair while time ago.

BlackICE was what I used prior to that little testing phase, but...
Agnitum Outpost was suggested to me by another m0n0 list contributor (/me 
waves) and thats what i still use.
It does seem a little flakey in the way it adds some apps twice to its 
trusted/rules list.... and it's MD5 summing completely ignores the file path 
(so 2 apps with the same .exe name will be seen as the same file 
irrespective of differeing path names), but at least it does checksums.
However I like its Ad Blocker plugin, and the log display is very nice 
(particularly if you are interested in how much data something is

I had a feeling someone with a deeper understanding of the relevant code 
would say something like that... Oh well, just a suggestion. :)
