Hello Adrian

I'm sorry there's not enough documentation to describe your use case, that's 
going to get fixed soon.

To work with an existing DHCP server, you still have to arrange to have it 
configured so that you can PXE boot.  On ISC DHCPD the "next-server" 
configuration option has to point at the MAAS server but the name of this 
option may vary depending on the DHCP implementation.

If you are unable to change this then you need to set up a separate network 
with your own DHCP as MAAS needs to be able to PXE boot machines.

Regards.
