A Communication Blocked window displays when a program is attempting Internet communication through a blocked port.
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?
Click Show details to show information about the program and its communication attempt. The following displays:
Local Program. The location and program on your computer that is involved in the communication attempt.
IntelliDefense Category. The IntelliDefense classification and description of the program. (More on IntelliDefense.)
Remote Address. The address of the remote computer or Web site that is involved in the communication attempt.
Direction. The direction of the communication attempt: Incoming or Outgoing.
Port Number. The port number that is blocked, and the protocol.
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.
Zone. The Zone that the communication attempt belongs to: Trusted Zone or Internet Zone.
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).
If the port is defined, the Defined Port settings will be updated to allow access (in the current direction and Zone).
If the port is not defined, a Custom Port rule will be created to allow access (in the current direction, protocol, and Zone).
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.
