DHCP relaying is the forwarding of DHCP requests received on one interface to the DHCP server of another. DHCP relaying is available for both DHCPv4 and DHCPv6. The settings can be found at Services ‣ DHCRelay.

DHCrelay binds to port 67 like other available DHCP servers. To run multiple servers side by side, use strict interface binding if available.
