Configure DHCP relay
DHCP relay allows a router to forward DHCP requests from one LAN to a separate DHCP server,
typically connected to a different LAN.
For the Connect IT Mini device, DHCP relay is configured by providing the IP address of a DHCP relay
server, rather than an IP address range. If both the DHCP relay server and an IP address range are
specified, DHCP relay is used, and the specified IP address range is ignored.
Multiple DHCP relay servers can be provided for each LAN. If multiple relay servers are provided, DHCP
requests are forwarded to all servers without waiting for a response. Clients will typically use the IP
address from the first DHCP response received.
Configuring DHCP relay involves the following items:
Required configuration items
Disable the DHCP server, if it is enabled.
n
IP address of the primary DHCP relay server, to define the relay server that will respond to
n
DHCP requests.
Additional configuration items
IP address of additional DHCP relay servers.
