    Ok. I am running a home network on my LinkSYS BEFW11s4 router. It is an older model running 802.11b technology @ 2.4GHz.

    I have 2 computers hooked up to it. I have 1 PC running wirelessly (which I have no trouble with) and I Have a MAC running OS 10.3.7 plugged into the back of the router/switch. I just added a 2nd MAC on the network last night and I don't understand what's going on. Here is my problem.

    What's happening is I am running two MAC's on my router which are both plugged into the back using standard ethernet cable. They are both set up to use the DHCP. One mac is running at 192.168.1.100 and the second one is set at 192.168.1.102.

    The problem is they have different WAN addresses on the network, but when they are connected to the internet, they both have the same IP Address. I have never seen this happen before?!

    ============
    (1st) WAN: 192.168.1.100
    IP: 64.173.171.180

    (2nd) WAN: 192.168.1.102
    IP: 64.173.171.180
    ============

    I need to know how to get these two computers to run on seperate IP addresses.

    Below are some settings I have in place on my router. Please help if you can.

    Thanks....

    The IP you see " 64.173.171.180 "
    should be your actual Ip, there won't be 2 for the same account and will only change when it is being released, providing it is not a static IP.

    The WAN IP address is the IP number you are receiving from SBC (your provider) as your real IP address (in this case 64.173.171.180; either fixed or through DHCP). Internally the router is using DHCP ( which you have selected; you could also have selected to use fixed internal IP-addresses).

    [Note: The way it is presented might give people the wrong impression that the actual LAN address (192.168.1.100-102) is the WAN address]

    The router is handing out IP addresses in the LAN (LAN is where your Macs are connected, either through wifi or UTP-cables) in the selected range. Therefore, your 3 Macs will have the mentioned IP-addresses x.x.x.100, x.x.x.101 and x.x.x.102. They all SHARE the one real IP-address you were given by SBC and the router keeps track of which machines requested what. If you want incoming connections to go to a specific machine you need to tell the router what to do via port-forwarding. That way one machine can act as a web-server reacting to all the port 80 (HTTP) requests that arrive at your address.

    Hope this helps.
