CirrusgRPC load balancing with F5 and nginx
I've a requirement of using gRPC through F5 using nginx at the server level which will convert port 80 to gRPC port (50001). Flow would be like: Client will hit F5 over port 443 which invariably will forward the request to nginx over port 80 which will convert it again over designated port of gRPC (50001). I enabled HTTP2 settings in F5 but application is not responding. Is there any specific setting which i need to do for gRPC at F5 level? nginx is already configured to forward request over port 80 to http2.

In addition to what has been already posted. You also have gRPC support being added in BIG-IP, starting with v16.1.0.
See K61517014: gRPC Support on BIG-IP
and also
K08041451: Configure a BIG-IP virtual server for gRPC traffic
Hi,
Update:
HTTP/2 full-proxy support was added two years ago with the release of v14.1.0.

"Important: The BIG-IP system supports HTTP/2 for client-side connections only. This means that when a client that supports HTTP/2 connects to a virtual server that has an HTTP/2 profile assigned to it, the resulting server-side traffic (such as traffic sent to pool members) is sent over HTTP/1.1."
ChetanAr_315803So gRPC uses HTTP/2 for server side connection. While troubleshooting further, F5 is converting HTTP/2 request to HTTP/1.1 at server side hence gRPC connection is failing. Any idea if F5 support HTTP/2 at server side?
