The traceroute uses udp and by definition, udp takes the best route at =
any given time; out of sequence arrival, etc.
Traceroute can only show you one way path, however, some versions of =
traceroute should have "-s" option which allows you to specify the =
source of the packet to trace from. If you got multiple nics, the -s =
will help you originate the packets from that particular interface using =
ip though not name.
You need someone at the other end to do the same and then you may have a =
complete turnaround path for that moment in time!

Hello,
I am looking for an option with traceroute that will show you the route =
you take externally
and back internally. Basically so if I am multihomed and I leave one way =
and come back
through a different circuit it will show both paths. Unfortunaly I could =
not find an option
with this. Does anyone know of a different version of traceroute or =
maybe a different program
or an option with traceroute that I do not know of ?
Thanks,
Mike
