[QUOTE="JigglyWiggly_"] I don't think Windows firewall stops any viruses or anything. All it does is block ports and services from being accessed. And it doesn't inspect packets either, you are going to need Snort to do that. i got snort running on my home router(pfsense, freebsd based), and it is so awesome. It lets me stop myself from causing attacks onmyself, that is awesome.
It most certainly does, I've seen it stop worm viruses replicating on a 200 computer network at the place I used to work as a junior admin, the only machines that werent effected were XP SP2 machines because of the firewall, my comment wasn't literal it doesnt stop viruses in the way a virus scanner will you're right, but it stops the spread of many of them across the network, if you've ever seen an infected machine try and push its infection to other PCs you'll know how and why.You said it yourself, the key words are inbound connections, a worm virus will be an unsocilited inbound connection which any untampered windows firewall will block without blinking.
XP sp2? Are you sure it's not because the OS was updated from the exploit? Could have just been unaffected by the virus. LOL I'm sure, you're in danger of argueing against your own logic here, without wanting to sound patronising go read up on what worm viruses are and how they spread, it doesnt take a networking genius to know that Windows Firewall will stop such malicious software, it'd be a bloody pointless firewall if it didn't LOL!
