dhcp relay

[Gergely Kiss]

It's not possible to use two or more DHCP servers reliably on a single
network segment, as you may never know which server gives a lease to a
particular client. It's because of the way DHCP works. A DHCP client sends
its request to the broadcast address and whichever server receives it first
will create a lease for that client.
The best solution, I think, is to use static (manually set) addresses to
printers, servers and other permanent equipments on your network.
DHCP relaying may work, if you know how to configure it, but I cannot help
with that as I never used relaying with Chilli.
Probably other users can tell you more about this.
