    Yes. I am using the correct external IP (public) as far as I know.
    When I use the public IP (which comes from my ISP) it works fine at
    home. But from any other location it does not work. I am using the
    correct port number because it works perfectly from the house but does
    not work at all from my office.

    I do not have DHCP running. I have each PC configured with a static
    IP. And it works perfectly using the correct port and using the
    public IP from home but does not work at all from outside the
    house(such as from my office or if I call any friends up).

    I do not have anything setup on DMZ. I am just forwarding the ports.
    It works perfectly when I use the correct port using the public IP
    from within my home but not at all from my office. When I setup
    Linksys to admin the router remotely. The public IP works perfectly
    from inside the house but not from outside the house(like my office or
    any other location on the planet).

    I do have some servers on the wireless net in the home. All servers
    whether they are wireless or whether they are connected physically to
    the router, they all work perfectly inside the house using the public
    IP(which is what my ISP gives me. I know what it is by looking at the
    status, WAN IP). When I use the private IP(internal) it works
    perfectly also using the correct port and such. This all works
    perfectly within the house whether it is wireless or not, using the
    public or private IP (IP on the router) using the correct port.

    But as soon as I use another PC outside my house the whole thing that
    I mentioned does not work and that is when I am using the public
    IP(from my ISP) trying to connect to any of the servers on the port I
    specified whether they are wireless or not. Nothing works outside but
    all works inside the house.

    So I figure I must have something setup incorrectly.

    Could someone please suggest something?

    Thanks
