The DHCP relay function cannot be used correctly

Tue Nov 08, 2022 4:22 am

The DHCP relay function is configured on the two MikroTik routers according to the Manual, but the relay function cannot be used.
After the DHCP server replies to the Offer packet, the relay server does not send the Request packet.
Speculation: The DHCP relay server does not receive the Offer message because the destination address of the Offer message sent by the DHCP server is the LAN port address of the DHCP relay server.
Check the captured packets, filter DHCP packets, and check the contents of packets No.489 to 492.
192.168.87.1 is the DHCP server, and 192.168.88.1 is the DHCP relay server
