    Hey, I just got a 27" iMac i7 and want to forward my ports for downloading torrents. I can't find any websites that clearly show me how to open the ports. I have a Belkin F5D8235-4 router. I'm having trouble setting up the static ip address.

    If you can find any sites that can show me or if you can please help!

    Also I need help finding my DNS! Thanks.

    Not sure about the ports, but for DNS settings:

    System preferences-->Network-->(choose your network connection on the left)-->Advanced-->DNS tab at the top

    Have you looked at PortForward?

    To set yourself a static address can either be done as a DHCP reservation on your DHCP server or you can go into Network Settings on your iMac and set a static address by changing the IPv4 field from DHCP to manual and then port the necessary settings in. This may cause conflicts in the future tho.

    To allow OS X to open the port, you should be able to just modify the Firewall and list that application as allowing incoming transmissions

    For the ports you need to go to System Preferences>Security, then the firewall tab, then Advanced, then the + sign and chosse the relevant app. That said, I prefer to enable uPNP in the torrent program and in the router, which saves a lot of unecessary hassle. Snow leopard doesn't seem to offer specific port forwarding, only allowing it for specific applications.

    For static IP, just pick something on the same subnet as your router, so if your router is then you'd set:

    router: 192.168.168.(any number between 2 and 254 that's not already used by a device on the network)
    Subnet mask:
    DNS:, (Google DNS servers),

    What if the what I am trying to port is not an application. I have an IP camera and I need to port 554, when I goto the firewall to add it there is no application for it. So again how do you open port 554.

    Thank you,

    This is your first post in this thread. How do you expect people to answer your question before you ask it? What is more, you didn't bother to give the model of your router. You have to give information to get information:rolleyes:

    Now to get you a little bit further down the road: I assume that your router is similar to my Linksys. If this is the case, then you are not restricted to ports assorted with common protocols. The router's administrative web page for access restrictions allows any port to be opened. You may type in the name of any application and the range of ports associated with that application that you want opened. You may then add this (these) port(s) to the existing set of open ports.
