The best FREE firewall?

Hello!

What is the best freeware firewall for Windows XP Professional SP2?

Windows' built-in firewall is too simple, sometimes applications bypass it.

Kerio Personal Firewall 4. I used to think ZoneAlarm, but got tired
of ZA's constant CPU-hogging (thanks to the buggy vsmon.exe module),
and got sick of ZA's constant forgetfulness about permissions (I always
had to tick "Remember this setting" between reboots, which sucks).

Kerio has the addded bonus of letting you prevent apps from launching
too, which is great if something you've run tries to launch a secret
keylogger in the background, etc.

(And yes, it's free if you don't want to pay for "pro" features).

I will try it. Thanks!

It only monitors incoming, not outgoing connection attempts. Kerio
catches Trojans by alerting the user to their attempts to call out.

Good luck!! Kerio 4 is a CPU hogging, bloated piece of crapware. I
wouldn't recommend that anybody install it. I tried it (1.2 GHz, 256M)
and it slowed my machine down to a crawl.

Google the groups to read the hundreds of horror stories about KPF
version 4.

I agree with you, and so do many others, uncluding regs in
and
others.

The best free Kerio firewall IMHO is version 2.15, without any
doubt. It is so popular that Kerio have very kindly continued to
make it available for download...
http://download.kerio.com/dwn/kpf/kerio-pf-2.1.5-en-win.exe

Kerio 2.1.5 does have one *small* security flaw in that it will
not block fragmented ICMP packets. However, it is simple enough
to suppliment Kerio v2.1.5 with XP's built in IP security feature
called "IPSec". More info on this here...

Version 4 is utter pants IMHO.

It's a little bit worse than that. Kerio 2.1.5 will not block ANY
fragmented packet. Let's them right thru, not just icmp, but TCP/UDP as
well. So IPSec won't help you there.

The best workaround for this problem is to run CHX-I 'behind' Kerio 2.
CHX will catch anything that Kerio let's thru, and the two work very
well together, no conflicts or problems.

CHX-I is available here for free. Just register and you'll get a free
license via email:

And if you can do without Kerio 2's outbound app control, then CHX-I by
itself is far superior to Kerio 2 as a packet filter.

It's worth visiting Secunia to see what unresolved security issues there
are for any firewall (or browser etc) of interest.

http://secunia.com/product/#software is an excellent site with hundreds
of software (and hardware) versions investigated.

Does this work in Windows XP SP2? Seems a bit outdated.

Yes, I've been using it for years, since Win98, through Win2000
and XP with all SP's. I'm using it now on XP Pro SP2.

Also, take note of Kerodo's comments as s/he may well be correct.

Thanks for that, I'll note your comments for future ref. It's not
something I've been concerned about for my own system as I'm
behind a router with built in security features which cover
Kerio's minor flaw.

Thanks! Will check!
I mainly want to block incoming and outgoing connections from some
applications.

(1) It doesn't stop apps accessing the net -- it only blocks incoming attacks.
(2) It doesn't stop apps launching other apps in the background.

Kerio does both. ZoneAlarm only does (1).

Different strokes for different folks: Kerio has made my PC much faster
and lighter than when I was using ZoneAlarm. In fact, ZoneAlarm caused
me to reset my PC due to 99% CPU lockups THREE TIMES in one day, which
was the final straw. Kerio is a superior app in my experience, and has
the added benefit of stopping apps from launching other apps without
your permission.

Aren't fragmented packets a bit of a problem to Kerio 2.1.5?
