NimbostratusHi,
http/2 profile has not been applied yet.
We found something unusual during the review before applying the configuration.
2) WAF <---------------> BIG-IP <-------------> Leaf
In this flow, the client is WAF.
Client Hello does not include ALPN because it is not a typical web browser.
Is it correct to not be able to use http/2 in an environment where ALPN is not included in Client Hello due to topology singularity?
Thanks.
I would say that you're correct. From what you describe, the WAF is acting as a reverse proxy. The limitation is on the WAF and not the BIG-IP.
If the WAF cannot proxy the ALPN extension, then you are going to have HTTP/1.1 on connection 2). I'm not sure if there is any way around this. Maybe the WAF software can be upgraded to support this? I'm assuming the WAF is different vendor hardware?
