VM-backup with vproxy to DD with multiple network segment

I have within a compagny one DD2200 attached for management over the management interface. I have for site-A one of the 10Gbps interfaces (4a) attached and routed to site-A and I have for site-B the second 10Gbps assigned and routed to the second interface (4b).

Within NetWorker I have just one pool to contain all backups, NDMP, Agents (ddboost) and VMWare (vProxy).

For each site I have defined a storagenode with 2 interfaces, one pointing in the LAN and one pointing to its backup-SAN (Either Site-A or Site-B).

If I create within NetWorker a datadomain device, I am able to let the storage-node communicate with their intended interfaces in the datadomain.

If I want to update/create the VMWare policy at this point, I am not able to assing one of the 3 possible interfaces of the datadomain. It is complaining about the host-name of the datadomain and you should use the single name of the datadomain. If I choose to use the management interface, with holds the hostname of the datadomain, or either NIC-name, I will not get an accepted connection.

After reverting all datadomain-volumes towards the management LAN, all works well, but all over the 1Gbps interface. The 10Gbps interfaces are ignored.

After changing the Networkinterface to 10Gbps path (by creating a devicename with the DD-10Gbps interface in its device path-name), the VMWare is failing again.

A) Is it possible at all? Or should I wait for vProxy 3.x (No ETA)?

B) During writing this epoch, I have a second solution (Create one DD-SAN, no Management, Add both 10Gbps NIC's in SAN, Rename/Disable Management, change IP-adresses to one SAN-segment for all DD-assigned channels) and will apply this one.
