Hi
Have someone successfully managed to get a LTM Policy to trigger on ALPN in "SSL Client Hello"?
I have created a policy like below, and attached it to a Virtual-Server.
But when I send/connect to VS, policy won't trigger and nothing is written to my log.
I have also tried with different Index values, but that makes no difference.
I have verified that the ALPN is present in TLS request, both with Wireshark but also with an iRule attached to same VS.
iRule:
WireShark:

I've been playing with this, but also couldn't get it to work. It's unclear what index the SSL Extension alpn in the policy would be a valid one.

Hi Niels
I really appreciate your help. For a while i thought i had done something wrong. But if you have tested it, and
also can't get it to work then I’m quite sure that it is a "bugg" in the way Big IP handles ALPN in TLS packages.
I will open a case towards F5, and see what kind of solution they will come up with.
