WireGuard?

The Mullvad VPN app makes it easy to use WireGuard.

If you prefer to use the WireGuard app download configuration files (requires login).

Here’s why we use and recommend WireGuard.

#
I use the WireGuard kernel module and can’t connect. Why do I get "Protocol not supported"?

Make sure the kernels and kernel headers that you are running match those from when you installed the WireGuard packages. If not, then upgrade them.

Try rebooting to see if the kernel module loads correctly: in a terminal, issue sudo modprobe wireguard && lsmod | grep -i wireguard.

Try installing and compiling the WireGuard source. Distribution packages sometimes don’t set things up correctly.

#
Why do I get low speeds using WireGuard on pfSense (when using snort) ?
If you use INLINE IPS then try setting it to Legacy mode and see if the performance improves after that.
#
Can I configure the VPN myself or do I have to use your software?
We provide WireGuard configuration files for any device that supports them.
#
Can I use Mullvad without the GUI?
Yes, by using the Mullvad command line interface. We also provide WireGuard configuration files for any device that supports them.
#
Do you support my OS or device?
We support Windows 10 and newer, macOS 14+ and newer, and Linux distributions such as Debian 12+, Ubuntu 24.04+, and the two latest Fedora releases. We also provide WireGuard configuration files for any device that supports them.
#
wg-quick fails, with the message RTNETLINK answers: No such device
This can happen if you set a MTU that is lower than 1280 in the WireGuard configuration file, make sure it is not set to lower than 1280 and then try again.
#
Mullvad app says that I have too many devices. How can I find which device has which device name?
You can find the device name in the Mullvad app settings > Account. You can find the device name for the WireGuard key if you log in to our website here: https://mullvad.net/account/devices
#
Can I purchase more devices for my account? I have reached the five devices limit.
We cannot add more devices to an account. You would have to get a second account or install Mullvad on a router with a WireGuard client to use it with all the devices in the local network.
#
How do I multihop with the app?
In the Mullvad app: Click on the Cogwheel -> VPN settings -> WireGuard settings -> Enable multihop .
#
Why Can't I connect using Comcast XFINITY router ?
If you have set it to maximum security, "which will block most applications except web browsing, email, iTunes and VPN." , try reducing it to typical to see if you then can connect. Or use port 53 for WireGuard.
#
Does Mullvad's VPN app support only tunneling a few applications (inverse split tunneling)?
No, MullvadVPN does not support only tunneling a few applications, also known as inverse split tunneling. Only tunneling some traffic could inadvertently cause leaks which are hard to detect. The Mullvad VPN app will always err on the side of secure by tunneling all traffic by default. If you understand the risks, our recommendation is to use the vanilla WireGuard app directly to tunnel only some traffic.
