ttl-exceeded sourced by arrival interface ?

[Julien Lesaint]

Hi,

This is a followup to the original post from James Jun, on Dec, 2003.

Quick reminder: in the case the route to the packet's source is not the
interface this packet arrived on, do we have a way to source ICMP errors
(ttl-exceeded) with the original interface's IP address ?

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,
