I have a few questions about your setup.
1) Are the subnets on the same physical network?
2) Do the boxes have multiple network cards?
3) If there is only one network card, do the machines have multiple
To give a machine two addresses, I'm pretty sure you're going to need
two interfaces per machine, possibly with one of them being a virtual
address. Each interface should have a different MAC address, so you
should be able to run DHCP seperately for each interface.
Am I missing something about your setup?
