LTM Healt monitor decrypt ECDHE

the only way would be for the client (F5) or server (server) to output the session key.

 

for a health monitor im not aware of any way to make that happen, perhaps the server wants to?

 

my question is why? you can easily replicate the behaviour with a curl or openssl s_client from the big-ip, why does the health monitor traffic have to decrypted?

    Thank you for reply. Thats the case.

     

    cURL in F5 bash is working and converted to http healt monitor is not responding but that's another case
