I tried "ifconfig lo -arp" (Linux) and I'm still able to ping the loopback interface from outside.

 

shouldn't it be configurable (to not respond to arp)?

 

Loopback interface is listening the request (because of the same IP address on LB) and I don't understand the flow of response... goes trough default gateway? because client (10.233.203.222 is on the same network than node)...

 

does server use loopback ip as source when responds to request from client/f5? if yes, i do not think it is an issue there.
