This is a Day-1 gap. A change in the app profile of the VS to enable Proxy Protocol doesn’t take effect today without disabling and re-enabling the VS, as it needs to be treated as a disruptive update, which hasn’t been implemented yet.
Resolution
Temporary Workaround:
For Proxy Protocol to work on L4 VS in versions 22.x and 30.2.x, the VS must be disabled and re-enabled for the changes to take effect.
Permanent Fix: The issue will be fixed in the following version.
