Hi Arno,

thanks for your suggestions!

Yes, it seems so ;-)

No they are in the same subnet.

Hmm, dynamic update is working, but when I'm connected per wire both 
network adapters are active ... I think this will not work, cause static 
IP assignment for different MAC accresses leads to some trouble inside 
the DHCP server.

Yes, but it seems so simple, that trouble from Murphy will come with it, 
too ;-)

I hope Kern would be able to schedule a solution into the roadmap of 
bacula for more than one IP or FQDN for a client.
