I need to choose a free port for something game-related. I will then unblock it on my firewall.

How do I determine:

a) What ports are free for me to use?

b) What ports are SAFE for me to unblock?

(My hardware firewall is kind of a pain so I may wish to leave this port open all the time.)

Thanks in advance!
