    To get a public IP address, you shouldn't be using a router.

    Can you explain what you are trying to accomplish?

    Did you purchase a block of public IP addresses from your ISP?

    Keep in mind, the computer you want to have a public IP address for need to be directly connected to the Internet to your DSL modem, not through a router.

    I currently own a D-Link DI-524 and I have a public IP set on my main PC.

    My PC is connected to port 1 on the router.
    My cable modem is connected to port 2 on the router.
    My other 2 PC's are connected to 3 and 4.
    My laptop is connected using wireless.

    My main pc ip is 70.*.*.*.
    My PC #3 is 192.168.0.102
    My PC #4 is 192.168.0.103
    My Laptop ip is 192.168.0.105

    So it is possible!!!
    Just keep trying and you will figure it out.

    From the previous post, not much detailed information on how anything is configured to be particularly helpful in figuring it out.

    For debibear,
    Can you post the IP address information each computer is getting?

    sorry bout that.

    on my main pc i have dhcp enabled on my network settings.
    and on my laptop and other 2 computers i have manually assigned the ip addy's.

    and my internet cable(the one from the cable modem) is connected to port 2.

    i hope thats better.

    SO instead of plugging the internet cable into the internet port i have it plugged into port 2. and i have dhcp turned off on my router.

    If DHCP is turned off on the router, what is assigning the IP addresses to the other two computers?

    cmosads,

    Again not a lot of details.

    What is the IP information on the other computers. This is more than the IP address.
    For example, what are the gateway and DNS IP address?
    Is this the same as the router's IP?

    How is the router configured?

    Are you using ICS?
    How does all that compare to the one computer with the public IP address?
    Do you only have one IP address assigned from your ISP?
    What is sharing the Internet connection if only one?

    Can all computers access the Internet independently or does one need to be on for the others to be online?
    But there is a lot missing from just how the cables are connected and an that IP address is assigned to share an Internet connection like this.

    Nortons might give you a problem trying to access files on your other computers but it shouldn't affect the internet.

    Some routers (DI-524 specifically) will not let you get an IP address automatically if you are connectig wielessly,
    try assigning an address by
    START>control panel>network connections>local area network> TCP/IP >properties and
    assign an address like X.X.X.200 X.X.X is your LAN subnet. The address exists on your LAN only. You may need to spec the default gateway as well. Us the one used by others computers on your LAN. You can get this address by "ipconfig /all" on a computer that is connected to the Internet.

    It would sure be good to know why they need all this. Perhaps none of it is necessary in the first place.
