If you can connect but cannot ping any hosts on the internal network and are using Windows Vista or above, please disable IPv6 on the TAP-Win32 interface.
You can do this by:
- Click Start
- Type “ncpa.cpl”
- Right click the TAP-Win32 interface and select properties
- Uncheck “Internet Protocol Version 6 (TCP/IPv6)” as per this
Then attempt to re-connect to the VPN.

When using Windows Vista or higher, you must run OpenVPN as an administrator. Running it as a non-privileged user will cause the above error and prevent the routes being correctly added to your computer.
