The existing logic (Range > 0) always triggered, because range is guaranteed to be at least 1 (a single port has a range of 1, a two port range (e.g. 80-81) has a range of 2, and so on). As such this could cause ports that had a host port assigned to them by the user to randomly assign one instead.

Fixes #8650
