It's important to note that mtr, by design, sends out ICMP packets, and
traceroute, by default, sends out UDP packets.
I suspect if you use the traceroute packages' traceroute command with the
-I switch on a host behind such a router, you'll get identical results.
If packets sent out with a TTL of, say, 30, come back with a TTL exceeded
message from the same host as packets with a TTL of 1, there is no software
method of determining the existence of the other hops. So I think this is a
case of garbage in, garbage out.
Let me know what you get.
