Communication Blocked (Port Closed Notice)

Displays when:

A Communication Blocked window displays when a program is attempting Internet communication through a blocked port.

Instructions:

The window displays to inform you that a port is blocked, and provides information about the program and its communication attempt. The window also gives you the option of opening the port.

 

Click OK to close the window or to close the current alert*.

* Note: Where several alerts show (for instance, various IP addresses are involved in a single communication attempt), you can click the Previous and Next arrows to view each of the alerts.

Where there is more than one alert, click OK to close the current alert or click Close all alerts to close the window.

 

How do I turn off all "Communication Blocked" notices?

To view program information

Click Show details to show information about the program and its communication attempt. The following displays:

Click the "Allow" link in this section to allow access for that port. The port will open and the settings for the Zone will update to allow access for the current direction and protocol. See "To open the port to communication" below for more information.

To open the port to communication

Click Show details and then in the Port Number section, click the link to allow access for that port. The text of the link has the direction and the protocol; for example, "Allow outgoing UDP access" or "Allow incoming TCP access". The next communication through that port will be allowed (the current attempt has already been blocked).

 

I see a "Confirm" window:

To turn off all notices

Select the Don't show these messages anymore check box to turn off future notices.

Note: Selecting this option turns of all notices, not just the notices for the current program or port.
