Detect Open/Closed Ports & How To Open/Close Them?
I would like to start using BitTorrent, but I don't know which port[s] to use. I'm using a 3-4 year old Linksys router and I think it acts as a hardware firewall but I'm not sure. A Linksys VOIP router from Vonage is in the mail to replace it. I have McAfee installed otherwise. How can I tell what ports are open/closed and how can I open/close ports? I would prefer to keep the amount of open ports to a minimum and share them with applications such as BitTorrent and World of Warcraft.
