Interesting thing I came across.  Surprised to see no talk of this in the forum yet.

Windows 10 OpenVPN 2.5_git (Wintun) "small issue or bug":
On Reconnect or Disconnect/Connect to a different AirVPN server: the previous Assigned IP(fde6:) is still present in the routing table along with the new Assigned IPv6(fde6:).
@go558a83nk
Did you notice this behavior?

I use pfsense so I'm not using openvpn on windows.  I just posted it here as I figured there would be some people who'd like to use it.

how do I hook up and use the Wintun driver with AirVPN ?

Add "windows-driver wintun" to .ovpn config, or
Add "--windows-driver wintun" to openvpn.exe command line
without the "quotes".
-----------------
auth sha512
windows-driver wintun
-----------------
Change the buffer like this if you want to achieve better speeds:
------------------
rcvbuf 562144
sndbuf 562144
------------------

thanks !

but, where do I configure OpenVPN ? I've never done this before for AirVPN, simply installed Eddie and used as is...

 

[Flx 76]

Under "custom OpenVPN directives." section in Eddie.
That is where you add your desired choices:
-------------------------------
windows-driver wintun
rcvbuf 562144
sndbuf 562144
------------------------------

does not work for me under Win 10 LTSC x64, Eddie 2.16.3... here's what I did:

1) Added the above directives to Eddie > Prefs > OpenVPN directives > Custom directives.
2) Then also uninstalled the current TAP driver via AirVPN (under Prefs > Advanced)
3) Rebooted.
4) Start AirVPN (it will say missing TAP driver and install TAP driver again), then I try to connect to any server. It keeps immediately aborting the connection and try another server... endless loop

Btw, since I installed openvpn-install-2.5_git_wintun-I607-Win10.exe, OpenVPN now pops up at every boot stating:

No readable connection profiles (config files) found.
Use the "Import File.." menu or copy your config files to "C:\Users\John\OpenVPN\config" or "C:\Program Files\OpenVPN\config".

do I need to configure something here ?

Thanks.

You must be using at least openvpn 2.5 besides the wintun driver.

I did install openvpn-install-2.5_git_wintun-I607-Win10.exe, and Win > control panel > programs and features states that that version is installed...

That's the wintun driver, not openvpn.

Look in your logs and it should say what version of openvpn is being used.

AirVPN logs say OpenVPN 2.4.6....

alright, so how do I install OpenVPN 2.5 ?

On their website under community downloads there is only the "OpenVPN 2.5_git wintun technology preview" package, which is a 4.4MB file, which is what I installed... so that 4.4MB is just for the wintun driver... ?

[go558a83nk 362]

I don't know.  Maybe I'm wrong.  But obviously the older version of openvpn is being used in Eddie.

cannot get this to work...

under Eddie > Prefs > Advanced > OpenVPN Custom path I entered the path of the openvpn.exe that came with the OpenVPN 2.5_git wintun install, then added the custom OpenVPN directives...

everything seems to be working, it finally prints "OpenVPN > Route addition via IPAPI succeeded [adaptive]"

but then hangs a bit and then prints "Windows WFP, Add rule failed: Interface ID '' unknown or disabled for the layer.:{2}" and starts disconnecting...

Any idea what is missing ?

Eddie probably needs updated for its network lock to work with the updated openvpn.  Turn off the network lock and see if that fixes it.

Not to confuse anyone here:
I use Native OpenVPN 2.5_git with wintun not Eddie.

I don't believe you can do that with Eddie client as of yet. Eddie will be updated ASAP to OpenVPN 2.5.x or maybe sooner. You can install the OpenVPN 2.5_git Preview from the official website on your own and do this yourself.

You need to import an actual yourairvpnconfigurationfile.ovpn file. Create that in Client Area->Config Generator.

Please be aware that wintun support functionality has been reviewed and merged into openvpn master. You can get latest snapshots from https://build.openvpn.net/downloads/snapshots/. 
For example, this is the current latest build.

The

windows-driver wintun

option must still be used in the VPN config, correct?
