Configure IPsec/L2TP VPN Clients

Read this in other languages: English, 简体中文.

Note: You may also connect using IKEv2 (recommended) or IPsec/XAuth mode.

After setting up your own VPN server, follow these steps to configure your devices. IPsec/L2TP is natively supported by Android, iOS, OS X, and Windows. There is no additional software to install. Setup should only take a few minutes. In case you are unable to connect, first check to make sure the VPN credentials were entered correctly.

Note: You may also connect using IKEv2 mode (recommended).

Note: This one-time registry change is required if the VPN server and/or client is behind NAT (e.g. home router).

If you get an error when trying to connect, see Troubleshooting.

Error 809: The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.

Note: The registry change below is only required if you use IPsec/L2TP mode to connect to the VPN. It is NOT required for the IKEv2 and IPsec/XAuth modes.

Although uncommon, some Windows systems disable IPsec encryption, causing the connection to fail. To re-enable it, run the following command and reboot your PC.

Windows error 789 or 691

Error 789: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.

Error 691: 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 remote access server.

For error 789, click here for troubleshooting information. For error 691, you may try removing and recreating the VPN connection, by following the instructions in this document. Make sure that the VPN credentials are entered correctly.

Windows error 628 or 766

Error 628: The connection was terminated by the remote computer before it could be completed.

Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate.

To fix these errors, please follow these steps:

For reference, see this screenshot of the VPN connection properties dialog.

Windows 10 connecting

If using Windows 10 and the VPN is stuck on «connecting» for more than a few minutes, try these steps:

Windows 10 upgrades

After upgrading Windows 10 version (e.g. from 1709 to 1803), you may need to re-apply the fix above for Windows Error 809 and reboot.

Windows DNS leaks and IPv6

Windows 8.x, 10 and 11 use «smart multi-homed name resolution» by default, which may cause «DNS leaks» when using the native IPsec VPN client if your DNS servers on the Internet adapter are from the local network segment. To fix, you may either disable smart multi-homed name resolution, or configure your Internet adapter to use DNS servers outside your local network (e.g. 8.8.8.8 and 8.8.4.4). When finished, clear the DNS cache and reboot your PC.

In addition, if your computer has IPv6 enabled, all IPv6 traffic (including DNS queries) will bypass the VPN. Learn how to disable IPv6 in Windows. If you need a VPN with IPv6 support, you could instead try OpenVPN.

Android MTU/MSS issues

Some Android devices have MTU/MSS issues, that they are able to connect to the VPN using IPsec/XAuth («Cisco IPsec») mode, but cannot open websites. If you encounter this problem, try running the following commands on the VPN server. If successful, you may add these commands to /etc/rc.local to persist after reboot.

Docker users: Instead of running the commands above, you may apply this fix by adding VPN_ANDROID_MTU_FIX=yes to your env file, then re-create the Docker container.

If your Android 6.x or 7.x device cannot connect, try these steps:

Docker users: You may set sha2-truncbug=yes (default is no ) in /etc/ipsec.conf by adding VPN_SHA2_TRUNCBUG=yes to your env file, then re-create the Docker container.

macOS send traffic over VPN

After trying the steps above, if your computer is still not sending traffic over the VPN, check the service order. From the main network preferences screen, select «set service order» in the cog drop down under the list of connections. Drag the VPN connection to the top.

iOS 13+ and macOS 10.15/11+

In addition, users running macOS Big Sur 11.0 should update to version 11.1 or newer, to fix some issues with VPN connections. To check your macOS version and update, refer to this article.

iOS/Android sleep mode

To save battery, iOS devices (iPhone/iPad) will automatically disconnect Wi-Fi shortly after the screen turns off (sleep mode). As a result, the IPsec VPN disconnects. This behavior is by design and cannot be configured.

If you need the VPN to auto-reconnect when the device wakes up, you may connect using IKEv2 mode (recommended) and enable the «VPN On Demand» feature. Alternatively, you may try OpenVPN instead, which has support for options such as «Reconnect on Wakeup» and «Seamless Tunnel».

Android devices will also disconnect Wi-Fi shortly after entering sleep mode, unless the option «Keep Wi-Fi on during sleep» is enabled. This option is no longer available in Android 8 (Oreo) and newer. Alternatively, you may try enabling the «Always-on VPN» option to stay connected. Learn more here.

Debian 11/10 kernel

To fix the issue with IPsec/L2TP mode, you may switch to the standard Linux kernel by installing e.g. the linux-image-amd64 package. Then update the default kernel in GRUB and reboot your server.

If you encounter other errors, refer to the links below:

Check logs and VPN status

Commands below must be run as root (or using sudo ).

First, restart services on the VPN server:

Then reboot your VPN client device, and retry the connection. If still unable to connect, try removing and recreating the VPN connection. Make sure that the VPN credentials are entered correctly.

Check the Libreswan (IPsec) and xl2tpd logs for errors:

Check the status of the IPsec VPN server:

Show currently established VPN connections:

Configure Linux VPN clients using the command line

After setting up your own VPN server, follow these steps to configure Linux VPN clients using the command line. Alternatively, you may connect using IKEv2 mode (recommended), or configure using the GUI. Instructions below are based on the work of Peter Sanford. Commands must be run as root on your VPN client.

To set up the VPN client, first install the following packages:

Create VPN variables (replace with actual values):

The VPN client setup is now complete. Follow the steps below to connect.

Note: You must repeat all steps below every time you try to connect to the VPN.

Create xl2tpd control file:

Start the IPsec connection:

Start the L2TP connection:

Check your existing default route:

Exclude your VPN server’s public IP from the new default route (replace with actual value):

If your VPN client is a remote server, you must also exclude your Local PC’s public IP from the new default route, to prevent your SSH session from being disconnected (replace with actual value):

Add a new default route to start routing traffic via the VPN server：

The VPN connection is now complete. Verify that your traffic is being routed properly:

To stop routing traffic via the VPN server:
