Comment (by MichaelBleistein):

 We have done a bit more research. In general other sftp clients like
 "Transmit" work without any problems on the same mac os x machine and the
 same user account. IPv6 connections are only a problem in cyberduck!

 During our research we found ticket #8848... It was resolved by putting
 utun0 on a blacklist of interfaces.

 Our machine also implements utun1-utun4 interfaces. So after removing
 these interfaces the behaviour changes. We do not get timeouts  anymore
 but "no route to host errors" immediately. It looks like cyberduck is
 still trying to use an interface with no internet connectivity.

 Is there a way to specify the interface cyberduck should use for
