This policy setting defines a list of TCP port numbers from which network traffic inspection will be disabled. Port numbers should be added under the Options for this setting. Each entry must be listed as a name value pair, where the name should be a string representation of a TCP port number. As an example, a range might be defined as: 8080. The value is not used and it is recommended that this be set to 0. If you configure this setting, network traffic inspection will be disabled on the TCP port numbers in the list. If you disable or do not configure this setting, network traffic inspection will be performed on all TCP port numbers.
