Enable/Disable in DHCP server
Ability to Enable or Disable DHCP by GUI
Just one or more scopes for sure (as it is with UTM9) ...
Are you wanting to stop just a single scope, or the whole server.
You can stop the whole DHCP server in System Services / Services
Very simple solution:
Just enable select "NONE" as a interface, which is possible ONLY if the subnet you want to define will not match any of the subnets on interfaces, otherwise will automatically switch it from NONE to interface with matching subnet :-(
yep very surprised that something so simple was overlooked
