Title: Use address from the last received UDP packet in UDP messages response

This patch fixes situations, where there is more interfaces / or / IP addresses on interface.
It forces to use the same source IP in responses, that was used as a destination in original request.

Originally, I created the patch on 1.3.1 branch (not public), but since it could be usefull for others, I applied it on the master and decided to share.
