Well, *I* would firewall eth1 from eth0 and cross-over eth1 to the ILO jack;
let the box be the firewall.  Sure, it's still as breakable as the box 
proper, but security-by-obscurity isn't *bad*, it's just *not good enough*.

It's another layer of tape.

Whether it's teflon or Gorilla is up to you.
