Is it possible to setup the ACS 5.x appliances to use two interfaces? I would like to have an ACS server with a NIC on a production network and also another NIC on an out-of-band management network. Looking at the CLI configuration guide it appears that you could setup Gig0 and Gig1 with different IP's and setup static routes for the appropriate networks. I'm not sure how the services bind to different NIC's and IP's though or if this will work. Looks like there was a feature request for this type of behavior in ACS 4.2 (CSCsr76897).
I have this problem too.
