Add a DHCP Relay

Using a DHCP relay, you can provide dynamic address allocation for clients that are not on the same subnet as the DHCP server.

DHCP relays don’t work when both client and server are reachable on the same physical interface.
  1. Go to Network > DHCP and click Add in the Relay section.
  2. Type a name.
  3. Specify settings.
