Hi, I actually have a all-in-one mikortik with static dhcp server and internet server with web-proxy and simple firewalling for a medium size network with computers and lan printers. If this server goes offline everything does, including network file sharing and printers (obviously, becouse ip’s cannot be given to the computers and printers). 
Then, I want to install a simply, but dedicated dhcp server with a mikrotik routerboard that ensures dhcp service -always- available to the whole lan (doesn’t matter if the internet server is down). That is the easy part, I have to disable dhcp server in the actual server and configure it in a new one, then plug it to the lan. 
The difficult part (at least the part I can’t figure out 
) is that the actual server has the lan interface configured as arp reply-only, and I want to continue that way, so if dhcp is in another server how could I get my arp list synchronized/updated correctly without duplicating each static dhcp rule in one server to my arp list in the other.
I wish some MK master can get it
