Your question is a bit unclear. Are you saying that whne you browse the Internet, the pages fail to load as traffic is sent over the VPN? If this is so and assuming you use the native Windows 7 VPN, you can make a minor change to address this. You simply need to use the local/default gateway for Internet traffic.
Right click on your VPN connection and click Properties. Then click the networking tab. Click Internet Protocol Version 4 and then click Properties and then click Advanced. UNCHECK "Use defualt gateway on remote network"
Repeat for Internet Protocol Version 6 if you are using this protocol.
If you are using a VPN clinet like Cisco, there is usually a similar option.
