Next, we terminate the CONNECT.
From the [headers](#headers), we know the target destination.
If the target destination has a waypoint, we enforce that the request is coming from that waypoint. Otherwise, the request is rejected.
If there is no waypoint, ztunnel will enforce RBAC policies against the request.
