conf: Allow to specify ranges and ports excluded from given ranges
This is useful in environments where we want to forward a large number of ports, or all non-ephemeral ones, and some other service running on the host needs a few selected ports. I'm using ~ as prefix for the specification of excluded ranges and ports to avoid the need for explicit command line quoting. Ranges and ports can be excluded from given ranges by adding them in the comma-separated list, prefixed by ~. Some quick examples: -t 5000-6000,~5555: forward ports 5000 to 6000, but not 5555 -t ~20000-20010: forward all non-ephemeral, allowed ports, except for ports 20000 to 20010 ...more details in usage message and man page.
