If you have a VPN established and routing setup correctly then a
traceoute will show only the main gateway for the VPN and the other
endpoint ... then any other routes after that.

Like this:

[johnny at myth kernel]$ traceroute 192.168.169.40
traceroute to 192.168.169.40 (192.168.169.40), 30 hops max, 38 byte
packets
 1  192.168.10.3 (192.168.10.3)  0.720 ms  0.424 ms  0.369 ms
 2  192.168.168.40 (192.168.169.40)  89.227 ms  87.933 ms  114.058 ms
