Is it possible that you are running an old version? I can not reproduce this with version 5.0.1 (from the ubuntu repositories, but looking at the .deb source package I can't see any added patches related to this). I tested this by having tcpdump listen for traffic on port 9102 and running a job for a node which has both v4 and v6 entries. The director immediately connected with v6. In fact, my backups depend on this functionality as on most nodes bacula is not reachable through v4. > > Suggestions?
