Hi GiacomoS, One example or reason for that is that we could have a Guest subnet that we want to be able to access LAN webserver. But : we don't want to give them access to any LAN, and no internal DNS is available. So we want them to go out and reach Public IP of MX, and then MX would realize it is destined for itself, and make them immediately come back in, to reach LAN webserver. So yeah, a real NAT loopback ( or Source NAT, Hairpinnig, U-Turn NAT or NAT Reflection as I've seen all around) is not a confirmed official feature for now ? if we want to create a real Hairpin, which is : LAN host only knows real Public IP of MX Internet port to reach LAN webserver. Is MX able to handle this kind of request from host and create functional back-and-forth traffic ? thanks,
