NAT64/DNS64 works very well, unless

 - someone uses literal IPv4 addresses to identify a service  (like,
   embedded references in http pages, loading some content from IPv4 
   addresses instead of hostnames)

 - that particular machine runs an application that does not know about
   IPv6 - most notably Skype.

A dual-stacked proxy would work, of course, but won't help for those 
problematic applications that want to do UDP but don't understand IPv6...
