They will still be able to talk to your Ray server, they just will not receive a DHCP address from it.

You can create manual leases in the DHCP server config. See dhcp_network(4). You would have to create a lease per DTU, which can get tedious, depending on how many that you have. Make sure you configure only manual leases in your config, so any machine that does not have a manual lease set up will not receive an answer from the server. With at least the ISC dhcpd (and maybe with the Sun one also), it is possible to group clients into classes based on specific conditional statements. A good way to do this is to use the dhcp-client-identifier. This class can be used in a group assignment in the dhcpd.conf file, which then has a subnet range of dynamic leases set up. See dhcpd.conf(5). The good thing about this solution is that you can keep adding DTUs without having to register their MAC addresses in the DHCP config. If at all possible I would separate the Rays from the PCs in the network. The last thing I would want to worry about is yet another interface on my servers to be secured against the barrage of threats coming from Wintels.
