Yes, but the intention was to use unique port numbers, although the test
still passed with 3 zeros.
Also, I'm not sure why this is a test for unspecified client address, if
host and port is defined. But I don't want to modify more than necessary on a
different issue then the one I'm doing the PR for.---
