    Firewall

    simple question ... what is the concept behind those Guys ?

    Ok ... dont go explaining what it does coz we are all aware of that ...
    but rather how does it intercept all incoming Connections and outgoing Packets and redirect safe incoming packets to the correct services ..???

    IMHO, I suppose it acts like a single terminal proxy server. Watches all incoming+outgoing TCP and UDP connections and blocks them according to the settings.
    penyou!

    You couldn't write a firewall in VB. At least not without having substantial chunks already written in C/C++ or another lower level language. And there's different kinds of firewalls -ex: Cisco router Access Control Lists versus SecureNAT.

    I already have wpcap and I use it a lot. This however does not allow blocking packets.
