We do this all the time because we have a lot of linux clusters with stuff
in the middle.
The simplest way to do this is as follows

It begins as a three way deal   backup server - storage node - client (two
way if your backup server is the storage node)
Make sure you have the correct dns name and the corresponding ip address in
the hosts file of all three machines.
When creating the client instance go to the tab where you have Backup
command and fill in there 
save -c public_clientname_to_be_backed_up
next make sure that in the saveset decription you actually enter what you
backup for that machine the mountpoint of the filesystem you want to back
up..
For windows cluster windows it works the same way 
Save - c virtual_client_name
Saveset must be the driveletter that is connected to the virtual machine
usually  E:\ or F:\

Now you do a test backup . on the backup server type 
[sudo] savegrp -mvI -c publicclient group_it_is_in &
Never done this on a windows backup server but it will be the same.
Hope this helps you

Subject: [Networker] Backup of Red Hat cluster nodes

I have two Red Hat Linux clients that form a Red Hat Linux cluster.  
Their data sits on an EMC SAN. I want to back up each node as a  
separate client. The problem is that NetWorker keeps trying to do the  
backup over their private IP address instead of their public address.  
How can I force the NetWorker client on these servers to use their  
public address? The NetWorker client and server are version 7.4.1.
