With Windows Vista/Windows 7/Windows 8 and OpenVPN/Viscosity, we sometimes have trouble accessing the internet and/or see the following error .
  • Warning: route gateway is not reachable on any active network adapters
This is a bug with either OpenVPN, Windows or the TAP driver and it usually happens when you have had your computer in hibernation and then wake it up again.

Try rebooting your computer. This often fixes the problem.

You might also see these error in your openVPN log file:
  • ROUTE: route addition failed using CreateIpForwardEntry: Access is denied
  • The requested operation requires elevation
The blackVPN version of OpenVPN - included with our easy installer - automatically runs as administrator. If you're not using our blackVPN version and you downloaded the standard version of OpenVPN you must run OpenVPN as Administrator. You forgot to start OpenVPN as an administrator. 
  1. Quit OpenVPN
  2. Right click on the desktop icon and select “Run as administrator”
