Am I missing something here or do you want to connect to a Private Network that 
is not present?
The client can connect to the Private IP only if it has a connection to that 
Private Network.
For that you need 2 NICs : 1 for Public and 1 for Private on both the TSM 
Server and TSM Client. You need a Private Network Infrastructure for doing 
backups thru' the Private Network. Once you get both the Server and Client 
connected to the same Private network you make the TCPServeraddress (in 
dsm.opt, dsm.sys )point to the private TSM Server Address.
Hope this clears the confusion. So do not waste time in blocking and unblocking 
ports untill you get your Private Infrastructure in place.
