    Hi, Ive got a macbook that I cant connect to my new xbox360.

    Ive tried connect360 and rivet.

    my public ip (whatismyipaddress.com) is 71.68.227.xxx
    my real ip (system prefs) is 192.168.2.x

    i was using programs peerguardian and little snitch. after disabling filters on both of these programs it still won't connect.

    Are one of theses programs masking my ip making it unable to connect to the xbox?

    I understand that we have a different public ip but is this something that I need to configure the xbox to?

    I tried that tutorial and I still can't connect to the xbox. Neither one seems to recognize the other. Ah well thanks for the info, I think Ive just messed up something on my mac to make it unrecognizable. Maybe I have to change some settings on the router or mac that aren't allowing network sharing.

    I selected AFP sharing for file sharing under "sharing" in system preferences. Not quit sure the distinctions between the three options for file sharing. These might not even affect the connection

    Are you trying to connect to the Xbox within your network, or are you trying to go outside to the internet and back into your network?

    If you are going out to the internet, you are probably getting blocked when you try to come back in by your firewall.

    I hooked up a security system to my network, and to get in to the server (to view the cameras remotely) I had to set up port forwarding on the router (opening up ports on the router, and sending them to the CCTV server).

    I would look to the forums for whatever programs you are attempting to use. I'm sure that others have run into the same issue.

    I'm not a professional, but if I'm right your router uses one IP address to represent all your devices to the internet (this way it saves IP addresses, and with IPV4 we're running out of IP addresses. Time to switch to IPV6). Your devices in your network will get an IP address from your router. This is almost always 192.168.1.something, or in your case 192.168.2.something. I believe is your routers address. Your macbook should be a number higher than that.

    This probably didn't help you, but it might clarify the differences in IP addresses.

    Forget about the public ip as you're working with private ip addressing in your lan.

    Make sure you can ping your xbox from your pc. If ping works then you can go on to the next step. If ping doesn't work then you need to find out why before you can try running a server on your network.

    Try the dnla servers you mentioned. Also try http://www.serviio.org.
