multi homed systems lniked together

[Ashley M. Kirchner]

Okay, someone tell me this makes sense, and is possible...please.

I have three servers that are all reachable on the net (they need to be, they're public machines.) Out of the three, one of them acts as a backup server for the other two - they dump files to it which then gets dumped to tape. However, these machines sit on two separate ports on our router, and even on different subnets. Consequently, whenever I transfer files across them, it's rather inefficient, going out the router then back in on the other subnet / port. Now, since the physical machines are sitting right next to one another, I thought I may be able to do the following:

- Drop an additional NICs in the backup server, configured with a private IP
- Drop an additional NIC in each of the other two servers, configured with private IPs
- Put all these machines on a separate HUB or Switch
- NFS export the backup partitions from the backup server to these private IPs, and mount them on the other two machines.

Theoretically I am now writing to the backup server through the private network as opposed to going through the router...yes? Did I forget anything? Is my logic flawed somewhere? Will the normal flow of traffic (with valid, public IPs) be interfered with at any point? Will packets start getting confused and not know what device to use?
