Hello,
I think we didn't really understand each other. I have several Loopback interfaces on the router, all of them have ip addresses. When I do traceroute from my network the router replies with ip 172.16.200.1 (Loopback0). On another Loopback interface I have a public ip address and I would like the router on traceroute or mtr reply that ip address.
Below is a traceroute from the current situation( Look at the point 2):
