Gents,

IIRC, the required network interface is not indicated by a hostname
active on that interface, but the name of the interface itself. In
Windows you can get that name by running ipconfig /all. This will list
the interfaces, you'll notice that by default the name is 'Local Area
Connection'. The advise is to change this to 'BackupLAN' and
'ProductionLAN', or something along that line. Use this name in the
Required Interface tab and it will work.

Regards,

Marcel
