number of hops using tracert over vpn

I work for a small tech company that is signing up a new client that has two locations connected via a site to site VPN. If I run tracert from one pc to another pc at the remote office, there are no intermediate hops. (I tried posting a pic bit my isn't high enough) Here is it typed out. My local ip address is 192.168.1.107

c:>tracert 192.168.2.9

Tracing route to 192.168.2.9 over a maximun numer of 30 hops

1 24 ms 20 ms 23 ms 192.168.2.9

Trace complete.

How is this possible? They are using Cisco routers (sorry, i don't the model # right now) and I do know it has a command line interface.

Any idea how this is achieved? Is this router specific? Is this possible with Cisco RV180W routers?

Thanks,

Kamal
