With a DHCP relay virtual server, OFFER packets from DHCP server are intermittently not forwarded to the client and dropped on BIG-IP.


Client machines joining the network do not receive DHCP OFFER messages.


It is not known exactly what triggers this condition, but it occurs intermittently when the DHCP relay virtual server is in use.


Enforce that the serverside flow is getting deleted, e.g. if dhcp server is broken, issue the following tmsh command: tmsh delete sys connection ss-server-addr cs-server-port 67
