Is there a way to stop relaying network traffic through VPN?
I assume you're using the "New Incoming Connection..." feature, which enables a PPTP server on the Windows PC.
The problem you're having sounds like a routing issue. The client is routing all traffic through your VPN server, but you only want to route traffic that is destined for your local LAN. Since this configuration is not defined by the PPTP server, this is always a client-side configuration issue.
On your VPN client, you will need to disable "Use default gateway on remote network".
- Open Network Connections
- Get Properties on the VPN connection you set up
- Under the Networking tab, get Properties on IPv4
- Click Advanced...
- Turn off "Use default gateway on remote network"
