but specifies whether or not a DHCP server should be started on a network interface. The
interface is entered in the standard form.
The synchronization of the DHCP server is switched on and off with "DHCPSync". The

/user/system/etc/basesys.ini. In subsystems, this variable is "DisableSubsystems", in
DHCPSvr "DisableDHCPD<INTERFACE>".
