Port Question

[hi_what_is_up!]

say if you do have a firewall you can customize what are the only ones that you should leae open and what are the ones that you should close.

close all the ones your not using :P

firewalls generally ask which ports each program (which tries to connect to the internet) is allowed to use. If you trust the program and have an up to date virus scanner (so your confident the program is ok) then just allow the program to use the ports that it automatically tries to use.
Afaik there aren't any ports you should need to permanently open.

If that doesn't help there are lists of what various ports are used for (try google).
