It does on my PPTP-based VPN back to my office using Kubuntu. Depends a lot
on how the tunnel is set up. The VPN server/concentrator you "dial" into
may reject certain ICMP packets which could prevent traceroute from
So in those cases I use "tcptraceroute" as it uses TCP packets (not ICMP).
Provided you use a port that isn't blocked, it should always succeed,
assuming there are no network problems. eg,
$tcptraceroute 126.96.36.199 80
Will try to trace to 188.8.131.52 on port 80. Provided that IP has port 80 open,
you will see the path all the way through.
VPN's aren't anything "special" - they are just a virtual link tunnelled
through another link. Usually the virtual link is encrypted but it's
fundamentally not all that different to normal layer 2 encapsulation
Be not anxious about what you have, but about what you are.
