One of the things I noticed when upgrading to 3.4 is that the clients connect to different ports than with 3.3. Now they always seem to go for port 49152 rather than something in the previous nfs range. It seems this is a feature rather than a bug, but it would be nice to mention it in any upgrade guide.

It's reported as a bug here: https://bugzilla.redhat.com/show_bug.cgi?id=987555
