Sorry about the title. Couldn't think of a better way to word it.

Here's my problem. I have a server (SERVA)running OpenSuse 11.1 that has 2 physical NIC's. One of the i/f's is connected via a crossover cable to a second server (SERVB). Both SERVA and SERVB are connected to the production network via their primary NIC's and to each other through the secondary NIC's using a 192. address.

SERVB is a backup server that performs backups of other servers through the production NIC then sends that data (as D2D backup) to SERVA via the secondary NIC to a volume called /data. It works very well and I am getting speeds of about 2.5gb/min from it.

What I would like to do is this. I want to have the /data volume on SERVA to only be accessible through the 192. address and not on the production network (10.). In other words, as far as the 10. network knows /data does not even exist (or cannot be accessed).

Is that possible?
