Everything works fine on windows Vista and windows 7 but I recently installed Windows 8.1 Pro on my laptop and no internet connection after connecting to my VPN.
The connection log shows no errors, not to my knowledge, could you guys please check and advise a solution:

I've tried older versions of OpenVPN, still no internet access, tried pinging it's all losses, tried reinstalling no luck, tried disabling AV and windows firewall again no luck. Ran devcon.exe in Windows 7 compatibility mode as well as As Admin still no luck.

Any help guys???

As this is only a problem for one W81 client .. make sure you disable the client firewall until you get a working connection.

You could try a different openvpn installer:

this indicates the NDIS-6 TAP driver ..

OpenVPN Community Edition version 2.3.x (Current):

Thanks for the help, but nothing of the above worked, I already tried turning my firewall and antivirus off but still no connection.
So finally I uninstalled OpenVPN and my antivirus (Avira) and restarted, reinstalled OpenVPN from the latest setup file one again, and voila got a connection this time 🙂

So I'm assuming, Avira was somehow blocking the connection???

Thanks once again!

Does "Avira" have a firewall ?

No but it configured and managed Windows Firewall, and even though I had Avira and windows firewall off, I couldn't get a connection ... always "limited connection"

But as soon as I uninstalled Avira and made sure windows firewall was disabled, I got a connection through OpenVPN.
