effective policy is `PERMISSIVE` (the default), the ztunnel will open a vanilla TLS HBONE tunnel (NOTE: this is not mTLS) to the Waypoint proxy and forward the traffic over that connection without presenting a client certificate. Therefore, it is absolutely critical that the waypoint proxy not assume any identity from incoming connections, even if the ztunnel is hairpinning. In other words, all traffic over TLS HBONE tunnels must be considered to be untrusted. From there, traffic is returned to the ztunnel...
