    I have just started settings up RealVNC on my network at home through an airport extreme. I'm able my machine from the other computer on my network through a web browser (via, but i'm trying to configure it to be accessed from outside my network.

    I have the ports, 5900 & 5800, on my airport forwarded to my computers IP address and when i test the connection it RealVNC it says,

    Your VNC server and network are correctly configured to accept connections over the Internet.

    However, please note that your server appears to be behind a NAT router with IP address 70.138.XX.XXX. If you are connecting from outside your LAN, then you will need to use this IP address.

    Does this mean that when i want to connect to my machine from the internet i go to 70.138.XX.XXX:5900?
    or: 70.138.XX.XXX:5800?
    or am i still able to use

    Any help is appreciated! Thanks!

    If you have a Dynamic IP address that changes often, you will want to setup a service like DynDNS that will give you an easy to remember hostname pointing to your IP address. That way you can type say to connect to your computer.
