    I want to set up a server for me and some friends for some uni work. I am sitting behind a wireless B broadband router model no befw11s4.

    Whenever i try connecting to my server by typing my internet ip address it connects me to my router. I am assuming that i need to set up some routes howver am unsure of what and how to do it and indeed if that is what i need to do.

    Can anyone help me.

    Your internet IP address is assigned to your router, not to the server on the local network. So everything is ok.

    The question is what services should be provided by your server and which ports need to be forwarded from the router to the server. As long as the router does not know that requests on port 80 (http) should be send to the internal IP address of your server the router will continue answering these requests.

    Just my 2 €-cents.

    Somewhat of a long process.

    First of all, I'm going to assume that you're on a broadband connection of some sort. To make things easier for your classmates to reach you, I recommend that you register with a dynamic IP service such as It will give you a URL (i.e. word web address such as:

    If you're on a cable connection, you'll probably have persistent dynamic IPs which rarely change. If you're on DSL, you're IP will change very frequently. Signing up with DynDNS will allow the service to monitor your IP and automatically send your classmates to your server. Otherwise, you'll have to let them know whenever your IP changes (which is a pain).

    Next, you'll have to assign your server (which is behind the router), a static IP address from your router. Meaning, you cannot allow the server to "get its IP automatically". Best way is to assign the server's MAC address to a specific IP.

    Depending on what kinda server you're hosting, you'll then have to forward the appropriate ports to the server. For example, if you set the server to have an IP of: and you're hosting a web server, then you'll have to forward HTTP service (port 80/81) to

    Some other minor tweaks will be needed, but this should get you started. Look for FAQs/guides on setting up a server with a dynamic IP broadband connection. :)
