It's all pretty much in the title. Is it possible to assign both local and public IPs to different nodes connected to the same switch?

I have 4 servers with 2 gigabit ethernet ports each. I want one of each to have a public IP, and the remaining ports to have local IPs for server-to-server traffic.

Sorry if it's a dumb question. I didn't see anything about it on here already.

We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs).
