Rule Search by Port
The following guidelines and uses cases are provided to clarify how Rule Search works when you search for rules by the port(s) they specify.
General Guidelines
Single-port searches generally work as expected. See Row 1 in the Use Case table.
When searching for a port range, the port ranges in the search and in the rule must match exactly. See Row 3 in the Use Case table.
When searching for rules that specify multiple ports, only rules that specify all of the ports are found. See Row 5 in the Use Case table.
