    Post 2 nic cards VS. one nic while sharing cable on lan

    Can anyone tell me why exactly you need 2 nic cards installed in the proxy machine to share a cable connection over a lan? I am using only one, and it seems to work fine. I'm using Spoon Proxy 2.2 and BlackIce Defender on the proxy machine. I recently configured the one nic card to have 2 IP addys, but it seems superfluous. I read everywhere that you need 2 nic cards to do this but why? What is the advantage over having one card?
    -Thanks

    How can you do it with one?

    You need 2 because one ethernet cable comes in from your Cable or DSL line providing the Internet to that Proxy or Internet Sharing Machine.

    Then you need one NIC for an ethernet cable that goes from this Proxy machine to a HUB so you can share the Internet Connection with your LAN.

    I,ll bet if that config works collisions would kill performace....

    Multihomed machining requires 2 nics ..
    Nic#1 for external ip..(216.65.xxx.xxx)
    Nic#2 internal ip,s for intranet(198.168.0.1)

    To get proper performance without collisions
    at your hub(yes you need a hub or switch)..
    connect modem straight to nic#1 (isp)
    connect hub to nic#2 and all others to the hub...easy

    Oooh, Oooh, I know this. Use two because if you use one the info will collide at times. I was using one and couldn't log on to half-life in multiplayer. When I put the 2nd one in it worked like a charm. I'm using WinProxy 3.0.
