[Gllug] Right way to route some traffic to a VPN connection

How is the VPN connection set-up?  Does the machine/router not route 
accordingly for the internal LAN so that selected (or all) machines on 
your LAN can route packets for the particular set of IPs on the remote 
LAN side?

Or am I talking complete gibberish here?

Regards,
