[Openvpn-users] Road warrior insecure? Or am I missing a crucial point?

1) I have a Lan at work using openvpn that is behind a hardware firewall (linux)
2) I have a Lan at home using openvpn using iptables firewalling (linux)
 
I can connect to the work Lan from home securely, as the only port open is 5000.
 
But... If I use a laptop and connect to the internet using dialup, then establish a VPN connection to the office LAN I see a critical security hole (please please tell me Ive set it up wrong). If I tracert (yes the laptop is running win 2k) to google.com then the packets flow out through the internet via my ISP etc etc.
 
Now what I see is two available connections.
1) via the dialup connector
2) via the VPN connection
 
Now How do I lock out normal internet traffic while being connected to the VPN server?
