DHCP Daemon settings do not sync to peers
DHCP Settings do not sync to peers in a CARP cluster, mainly because of the failover IP must be preserved.
There may be a way around this limitation, or perhaps a way to assume the failover IP for the remote if configured on the master. It should be the IP on the corresponding interface on the master. (e.g. Master LAN is 192.168.1.2, Backup is 192.168.1.3, failover peer on Backup should be .2)
