I'm using a remote-site VPN (ProtoVPN).

When I tracert to the IP address of the VPN server, the hops through my ISP and other intermediate hops before the VPN sever are shown.

But when I tracert to other addresses, say google.com, these intermediate hops are not shown. Why?

Can VPN affect the traceroute protocol?

  1. Traceroute is not a protocol. It is an application that uses ICMP (Windows) or UDP (*nix) packets with short TTL values. It relies on ICMP error messages to determine the hops.

  2. VPN tunnels act as a single hop, so yes using the tunnel will affect your traceroute results.
