Dhcp server will grant ip for green and blue nets (not orange)
Is it a bad idea? Ns-dhcp does not seem to be able to grant ips to remote networks (the NS router server has dhcp-relay enabled: NS as dhcp relay agent).
(I currently have a debian running in this way, but I am evaluating changing it to NS)
I never tried the DHCP relay, so I don’t know how dnsmasq behaves in such scenario.
Even if it’s not a bad practice to put the DHCP server in the DMZ, I think you’re over complicating the configuration.
Just put the DHCP server on the gateway and configure it to listen only on blue and green.
Server on the DMZ should have a static IP address.
