Chrisbees Posted December 29, 2009 Share Posted December 29, 2009 All of my ports appear to be blocked. How is this possible when my firewall is off and I am connected straight to my cable modem? If I enable the firewall and select enable stealth mode I can scan my ports and it shows stealth but if I disable stealth mode it shows closed. Also has anyone ever gotten MiniUPnP to compile on OS X? I can't seem to figure it out.

If you have modem/router all in one then you may need to enable port forwarding in its setup otherwise your ISP can be blocking the ports by default.

No, I have read that ports < 1023 are blocked by OS X. I can disconnect from the VPN and connect to 1024 and up. http://viceroy.eeb.uconn.edu/Biota2Pages/support.html tells about needing to run in root to use these ports but I am lost since its talking about things that no longer exist on OS X like Netinfo Manager. Vuze even says this "Testing port 444 ... Unable to test: Invalid port given, or test service failed. Another application may already be using this port.. (Can't initialise server: Permission denied)."

One thing I have found though when trying to use Vuze or any other torrent application is that using a popular games port is the idea, works well with my ISP as they can't block those or people start complaining to them.
