You need to specify the port numbers used at the source and the target for the attack traffic. The available options are listed below:
You can use the keyword "any" to specify a wildcard port number.
You can specify a port range using the range operator, colon.
Example: 1:1024. This indicates that the port must be between 1 and 1024, both inclusive.
Example: 100: This indicates the port must be equal to 100 or more.
Example: :500. This indicates that the port must be less than or equal to 500.
You can use variables to indicate ports.
