Adding to a pre-defined protocol

You cannot add a port number or IP address directly to a pre-defined protocol. You can, however, create a custom protocol with the same name as the pre-defined protocol, and then add ports or IP addresses to its definition.

When a custom protocol and a pre-defined protocol have the same name, web protection software looks for protocol traffic at the ports and IP addresses specified in both definitions.

In reports, custom protocol names have a “C_” prefix. For example, if you created a custom protocol for SQL_NET and specified additional port numbers, reports display C_SQL_NET when the protocol uses the port numbers in the custom protocol.
