Create program exceptions instead of port exceptions

If you need to allow unsolicited incoming traffic through Windows Firewall, create a program exception instead of a port exception. When you create a program exception, Windows Firewall dynamically opens ports for the specified program and then closes those ports when the program is shut down. When you create a port exception, the specified port is open all of the time, which makes the computer more accessible to attack.

For more information, see Configuring Program Exceptions.
