The IP address sent by the PC 0000 is replaced with the downlink IP address of the DHCP relay agent 111254 the IP address of the relay agents interface at which the DHCP Discover message was received. This request forwarding is done by the local router gateway of the DHCP client.

DHCP server is located at IPv4 address 10014. Make sure the Firebox has a route to the IP addresses you specify for DHCP relay. This tutorial will explain how to configure DHCP Relay on Cisco Switches using the ip helper-address commandNote.

In the Network Adapters page look for the Management Interface DHCP Server pane. Enter the IP address of the DHCP server where the FortiGate unit obtains the requested IP address. Dynamic Host Configuration Protocol DHCP relay is used to forward DHCP clients broadcast request DHCPDiscover from one VLAN to the DHCP servers VLAN.

DHCP relay does not choose the particular DHCP server in the dhcp-server list it just send the incoming request to all the listed servers. The relay agent inserts the IP address of the interface on which the DHCP clients packets are received into the gateway address giaddr field of the DHCP packet which enables the DHCP server to determine which subnet should receive the offer and identify the appropriate IP address range. Router receives DHCP client requests on eth1 and relays them to the server at 10014.

Then skip to the Configure IPv6 DHCP. If this is chosen enter the IP Address of the remote DHCP server in the IP Address IPv4 field and click Next. Relay agents receive DHCP messages and then generate a new DHCP message to send out on another INTERFACE.

It allows local hosts to acquire dynamic IP addresses from the remote DHCP. Relay Agent IP address. For more information read this topic.

Network administrators can use the DHCP Relay service of the SD-WAN appliances to relay requests and replies between local DHCP Clients and a remote DHCP Server.
