 My master backend is in a different subnet than some of the frontends.  So
 I have a port forwarding do the backend in the router that is in between
 the backends:

 The backend is locally 192.168.1.106.
 To the troubled frontends it is 192.168.0.105.

 I have the setting MasterServerIP 192.168.0.105 in the db for each
 external frontend. This works so far as that the frontends connect to the
 backend and get e.g. the recorded list, can watch recordings etc.
 But they can't watch liveTV or shows being recorded at the time (which is
 sort of the same thing, technically).

 What happens is they try to reach the backend under the wrong IP
 (192.168.1.106 instead of 192.168.0.105).

 Maybe the backend looks up the hostname in some situations instead of
 leaving it to the frontend?
 Preview pictures and preview videos don't work for the same reason.

 I use ubuntu gutsy ppa (svn-trunk) packages from https://launchpad.net
 /~mythbuntu-trunk/+archive but the problem exists in standard ubuntu svn-
 fixes packages also.

 Here's the shell output:
