By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries! They can't get in to your computer, and your computer won't try to send them anything either.

Port Allow List

The new "Port Settings" tab allows you to unblock ports (incoming and/or outgoing). This means that PeerBlock will not filter any connections from/to those ports. This can for example be used if you're running PeerBlock on a public FTP server, or if you want to ensure that outgoing SMTP mail communications are never blocked.
