    you should be able to get to any address, providing the routing has been set up.

    Your local PC should have a default router setup. This is where TCP/IP on your local PC sends its requests for any packet that has an address that is not on its local network and does not have a static route already setup.

    So, the sequence should be -
    1) user makes request to connect to 10.0.0.225
    2) TCP/IP on local PC sees if it already has a route (either static [ie. coded in /etc/routes] or dynamic [ie. already found this one by the following method])
    3) If a route already exists, then local TCP/IP will "know" where to send the packet of information (ie. where the next hop is)
    4) If no route exists on the local PC, the local PC's TCP/IP will take the address of its defualt router and send the packet there. It is then the job of the default router to establish what the correct route it to 10.0.0.225 and pass the packet onto the correct next hop.

    One last thing. If your don't have a dot separated address (such as 10.0.0.225 ) but an address such as www.linuxforums.org , then your local PC's TCP/IP will have to first go to it's default dommain name server (DNS) and get a dot separated address (ie. what www.linuxforums.org really is - 67.19.135.122).

    Hope this points you in the right direction.

    Have fun
