    Network Security: Firewalls, DMZ, etc

    Hey again. As some of you know i recently setup a network for a friend, and enabled the internet to be shared by all computers attached to the network. The current setup utilizes no firewall or security, and i dont want to leave his static ip setup unprotected. I am thinking of using zonealarm, but dont know how i should set it up, ie what ports and things to block, as i know firewalls are a pain with some programs like aim or kazzaa. Should i just load it standard?

    Also, i have heard about something called a DMZ, is this better then the firewall? What firewall do you reccomend? This isnt NASA were wrapping up, if it was a high risk type of thing i would order a hardware wall.

    Thnx.

    Windows XP comes with a built in firewall...

    Don't bother getting software firewalls, rely on XP and if u want superior protection get a hardware firewall/router... if this guy is a gamer he won't appreciate the cpu strain that a firewall ontop of the router service that is running on his pc - a hardware option will save him this and probably future headaches.

    Also talk him into a NIC card with built in net processing to further reduce the strain on his cpu.

    A DMZ is a comp with no firewall protection which means all it's ports are open to the net - so u don't want anything important on that PC - a DMZ is usually for a PROXY - im not clear what u need to run on the DMZ machine to make it a proxy but the info is out there - it's basically an advanced router.

    I appreciate the reply, but xp's built in firewall is a JOKE, seriously i wouldnt trust that with my worst enemies credit card numbers :P

    >>if u want superior protection get a hardware firewall/router

    The hardware firewall is much much more than needed so i dont really consider it an option. The router is out, i hate those damn things.

    >>if this guy is a gamer he won't appreciate the cpu strain that a firewall ontop of the router service that is running on his pc

    Hes not a gamer in the sense that this would matter. There is no router on the system.

    >>Also talk him into a NIC card with built in net processing to further reduce the strain on his cpu.

    The NICs i used do have this.

    i higly recommend tiny personal firewall available here
    http://www.tinysoftware.com/

    it is free(used to be looks like a 30day trial only now) and im my experience a very robust firewall...
    it is fairly complex to set up though so i hope this wont be the first firewall you are configuring
