Currently the box is sending ttl-exceeded with the IP address of the interface the route to the sender is pointing at. No need to explain why such a feature would be useful - primarily for traceroute comprehension & routing troubleshooting, rather than for some cosmetic purposes. Regards, -- Julien Lesaint.
