--dport— Specifies the destination port of the UDP packet, using the service name, port number, or range of port numbers. The--destination-portmatch option is synonymous with--dport.--sport— Specifies the source port of the UDP packet, using the service name, port number, or range of port numbers. The--source-portmatch option is synonymous with--sport.
For the
--dport and --sport options, to specify a range of port numbers, separate the two numbers with a colon (:). For example: -p tcp --dport 3000:3200. The largest acceptable valid range is 0:65535.
