BIG-IP TCPDUMP Question

Hi Willian, What do you mean when you say initial packets? TCPDUMP output depends on how you are using it. What type of VIP is present on which you are taking tcpdump? Is it L4 or L7 ?

What does it mean when the tcpdump is only receiving the initial packets and nothing else?

if you are using pva, turn it off (pva-acceleration none) and try again.

if you are not using pva, you may check if there is asymmetric routing (i.e. server sends response to client directly - bypassing bigip).
