Configure separate LAN for backup data transfer

Hi Experts,

I have installed and configured my master server under veritas SFHA cluster. But not for my media server.

Currently I also configure 2 separate LAN connection for both master server and media server. I quiet dummy about network. 1st LAN connection is routable and the 2nd LAN connection is not routable for security issue. Is that possible to configure only backup data to use the 2nd LAN since all client server is only alowed to communicate to the media server using the 1st LAN from storage?
