Windows 10

The following instructions were tested on a Windows 10 system. Setup on other versions of Windows will be similar, but the dialogs and messages seen may not be exactly as shown here.


Not using Lets Encrypt?

If you using the built-in ACME system for managing a Lets Encrypt certificate then you can skip this Certificate section and jump to the sectoion below to just set up the VPN credentials.

Download the Certificate

This is not needed if you are using Lets Encrypt on the FireBrick The CA certificate needs to be installed on the Windows machine using an account with administrator privileges.

First, download the CA certificate in DER format to the Windows machine. The easiest way to do this is to@

  1. Use a browser (e.g. 'Edge') to visit your FireBrick
    1. Go to: Config - Certificates to reach the certificate management page
    2. Click on the Download DER link corresponding to the CA certificate.
    3. Save it in a suitable location on the Windows machine. Note that you must download the certificate in DER format - windows machines do not recognize PEM format. The file will be given the .crt extension.
  2. If using the 'Edge' Browser, then click the Open button once the file as downloaded

Install the certificate

  1. You have downloaded the CA certifcate in DER format, and you'll have a file ending in .crt
  2. Double click on the file to open it, you may get a Warning (see screenshot)

    • VPN Provider: Windows (built in)
    • Connection name: (What ever you like, e.g. Office)
    • Server name or address: The IP or host name of your FireBrick. (the Server name needs to match the name in the generated certificate, this is usually a hostname rather than an IP address)
    • VPN type: IKEv2
    • Type of sign-in info: Username and password
    • Username & Password (as set up on the FireBrick). This is optional, you can leave blank and Windows will prompt you for this information each tie you connect.

Connect

You should now be ready to connect - There are a few ways to connect, the easiest is to click on the Network icon near the clock, and the VPN connection should be at the top of the list. Otherwise, you can connect via: 

Start/Windows icon -> Settings -> Network & Internet -> VPN

If not already saved, you'll use the username and password as set up in the EAP Identity on the FireBrick (in this example, we had set up a user of fred with a password)

You probably want to change the type of network to Work Network after the connection establishes.


Windows not setting the VPN as the gatweway?

On our Windows 10 machine, the VPN connected, but traffic was still going out via our normal network connection and not over the IPsec VPN. e.g., a tracert shows traffic going via our local router and not over the VPN.

We were also unable to open the TCP/IP properties of the VPN connection. Others seem to have the problem, e.g. here and here, but those post are about preview releases and our Windows 10 is the final release. The button isn't grayed out on our case, it just does nothing when clicked!

The problem with the routing, is that the VPN connection is set up by default for 'SplitTunneling', which is not supported by the FireBrick. The way to disable SplitTunneling is via the command-line tool 'PowerShell' which is included with Windows 10, here is how:

  1. Load PowerShell via:
    • Start/Windows button -> type: PowerShell -> Click on 'Windows PowerShell Desktop app'
  2. Type the following command to list the VPN connections:
    • Get-VpnConnection
  3. You will notice the Name of the connection as well as the 'SplitTunneling' setting being set to True.
  4. Disable SplitTunneling with the following command:
    • Set-VpnConnection -Name "[vpn name as listed in the above command]" -SplitTunneling $False

(If needed you can re-enable SplitTunneling by changing False to True)

  • Powershell screenshot

  • Disabling SplitTunneling on Windows 10 via PowerShell


Help

IKE authentication credentials are unacceptable

 
Error: IKE authentication credentials are unacceptable

Check that the hostname as set in the VPN settings matches the server certificate name

The remote connection was denied

The remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remove access server

 
The remote connection was denied...

If all else looks correct then be sure the FireBrick is running software release of 1.36..009 or greater.
