I want to know if any port of my machine (Mac OSX) is forwarded or not. I googled for quite sometime but couldn't find anything for the same. There is a network utility which tells which ports are being used but there is no information about which local port is forwarded to which remote port.

Please let me know if anyone knows of such utility.

If you want to check and see if you have ports open correctly use Put in the port that you have forwarding set up on and it will tell you if it is open or not.

I can know wheter a port is opened (used ) or not using utilities like portscan, netstat etc but i want to know whether an opened port is forwarded to some other port on the mac machine. – Rajat Oct 14 '11 at 7:31

Port forwarding is probably done by your router check to get help to forward ports on your specific router

This port is forwarded on a local machine as mentioned in the question and not a router. So doesn't help. – Rajat Oct 14 '11 at 7:32
