i’m not of the same idea, sometimes dhcp could be useful also on orange. ie it could be used to have a tftp server on dmz to deploy new server, or when restoring template of vm, or if i connect a new appliance on dmz i could simply connect the cable , verify the ip and then configure it.
honestly, i can live without this option, but if it’s not too hard to develop… why not? maybe could be useful to someone…
