is it possible to make 1:1 map of one TCP or UDP port like that: everything that goes from anywhere to 200.10.10.10 port 12345 should be mapped as it would go to 10.1.1.1 port 33333 everything that goes from 10.1.1.1 port 33333 to anywhere should be mapped as it would go from 200.10.10.10 port 12345.
