from 'man ipfw'

             With the TCP and UDP protocols, optional ports may be specified
             as:

                   {port|port-port|port:mask}[,port[,...]]

             The `-' notation specifies a range of ports (including bound-
             aries).

             The `:' notation specifies a port and a mask, a match is declared
             if the port number in the packet matches the one in the rule,
             limited to the bits which are set in the mask.
