I was just wondering this,

How does firewalls actually work?

I mean, Not the dumb Ver, that firewall is a hardware or software device which is configured to permit, deny, or proxy data through a computer network which has different levels of trust..

I want the Scientific Way? if possible

If it's not enough, here's lots of other links:

With out all of the technical crap.  It filters out specific internet traffic, as well as monitor what programs want internet access.

A (working) firewall intercepts.

That's how this thingie works.

It intercepts (by it's original definition) all ingoing and outgoing attempts to connect between (be it from outwards or inwards) YOUR PC and / or another PC / Network (including Intranet, Internet and others...)

Mystery?

Cheers...
