BIG-IP production traffic flow.
We are connecting ‘externally’ using ‘https://www.xyz.zbc.com/yyy/123 which is then ‘translated’ to correct url in reverse proxy config. Secure communication is terminated on first BigIP. Second BigIP acts as load balancer. Port 8080 is to be used through the whole ‘chain’ to Presentation server(real server behind the second LB).
We observe that even when connecting on port 8080, the Presentation server responds on 8043. The BigIP and/or reverse proxy expects response on the same port as sent, meaning it’s expecting response on port 8080 (not 8043).
Any suggestions or doubts on why this may be happening?
