I have a PPTP VPN setup at a client on 2 different WAN connections.
The VPN works and connection on both but I cannot access any LAN resources except for the Peplink management page.
I can access the internet however and a trace reveals that the traffic is going over the VPN.
I am on firmware version 6.2.2 on a Balance 30. I will upgrade software today and see if that makes a difference or not.
