As to why people wouldn't put them behind dedicated firewalls, imagine
something like a single-server colo scenario. Most such providers don't
offer any form of lights-out management aside from maybe remote reboot
(power-cycle) nor do they offer any form of protected/secondary network
to their customers. So, if you want to save yourself from a trip, you
chuck the thing raw on a public IP and hope you configured it right.

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.
