In certain configurations, and when the BIG-IP system does not have a directly connected route to the request sender, proxy ARP may fail, leading to dropped ARP replies.
ARP replies are dropped, leading to connection failures.
-- Running v18.104.22.168 or 22.214.171.124 with engineering hotfix 0.89.2. -- ARP requests and replies are processed by different TMMs. -- A directly connected route to the request sender is not available.
Create a self IP in the same subnet as the ARP request senders. This creates the necessary directly connected route.
