Does anyone have a working example of configuring an MX series router to do NAT-PT with the same incoming and outgoing interface? When we acquire other companies we always have the issue of overlapping use of 10.x.y.z. I'm hoping to solve this with each site having a router on a stick advertising a /96 IPv6 prefix gets NATted to 10.x.y.z. Is this possible? This needs to allow IPv6-only hosts to access IPv4 host, but not vice-versa. Is this possible?
