To be considered as a local server, a way is to give many ip to the urbackup server, one on each lan.
However, you can only specify a single adress for the agent to use for restoration.
If that adress, is located on another lan and not reachable (that was the point of multihomed setup)
The backup will works fine and the local server ip will be shown sucessfully.
However restoration from the agent is not possible
Only restoration from the server is.
Could the agent use the local server ip as fallback ip for the restoration?
