    Creating a Firewall

    I'm interested in how a firewall is created. Yes, I've checked out the Winsock SPI reference on MSDN. Personally, I find it cryptic and am asking for a further explanation. Just a basic where to start should suffice.

    Check out this article on the Filter-Hook Driver technique
    We haven't inherited Earth from our parents; instead we have borrowed her from our children - old Indian saying.

    Yeah I've seen that one. It doesn't seem too great though.

    ##NO BUMPING PLEASE##

    Yeah, I know that SPI documentation is pretty weak....but if you follow the "layered" (I think that's what it's called) example they give, you should be able to get to grips with it - I didnt though....I gave it a glance and decided I couldnt be bothered

    There are other ways - some confined to newer platforms, some requiring a driver

    Here's a brief outline http://www.ntkernel.com/articles/firewalleng.shtml
