    Hi, how does a software firewall really do its work to protect our information online? I am trying to picture in my mind how it really somehow fortresses any information coming into going out from my computer.
    Anyone out there have any technical info on exactly how a firewall does its job?

    I`ve got an excellent firewall that gives me a "true stealth" rating on testing sites,but it seems there is a lot more to a firewall than just installing it custom setting it.
    Thanks for any information
