I am pretty sure I know the answer to this, but 2 technical people in my organization cannot agree, so I'm putting this on ServerFault to get a final opinion.
We have a relatively simple set up in a data center:
- About 6 servers connected to an unmanaged Dell switch providing various web services.
- The Dell switch has the plug from our network provider.
We want to do file transfers between 2 servers to keep them in sync. Each server has an external IP and an internal one (ex: 192.168.0.5).
Is there an advantage to connecting the 2 servers doing the transfers using the internal IPs rather than the external ones?
