Download Wireguard For Windows
Tunesha Brown
I have multiple computers (Win10 pro) placed at different remote locations (my partners) that I need to manage. I need to access them from a central location. So I have a central VPN server, and I want multiple Win10 pro instances to connect to it. I'm using L2TP, but I would like to migrate to wireguard. With L2TP, it is possible to start rasdial.exe in the background, from the task scheduler. The main goal is to start the tunnel as soon as the computer starts up, and automatically reconnect if the tunnel goes down. I need this BEFORE any user logs into the computer (e.g. in the background). I wonder if the same can be done with wireguard?
But I think it is for configuration only. I think it cannot be used to activate a tunnel. The original documentation ( -line-interface ) explains that "the interface can ... be activated with ifconfig(8) or ip-link(8)" but of course that works for unix only. In that documentation, there is another note "Non-Linux users will instead write wireguard-go wg0" but I'm not sure what they mean here. There is no program name "wireguard-go" anywhere. The network adapter for the tunnel only shows up in the network adatpter list when the tunnel is already active. E.g. there is no network adapter that I could "enable" or "activate" when the tunnel is down. Finally, there is wireguard.exe. When started without parameters, it is a GUI application. It cannot be run without a logged in user and a desktop, and it does not activate any tunnel automatically. It has some interesting command line options. "wireguard.exe /managerservice" is used to start it as a windows service. "wireguard.exe /tunnelservice CONFIG_PATH" looks promising, but I was not able to start that. I get this error, that "the process could not connect to the service manager" or something similar. (I also get this error when I start it as administrator.)
When you use wireguard.exe to import a tunnel from a .conf file, it will read it in, sanity-check it (mine failed because I accidentally hit the keyboard during copy/pasta, so it rejected the Base64 encoding), and then safely store it away in the DPAPI storage. You can then delete your original .conf file. Just do this, it's better.
OK so here's the bit that I only fully realised tonight: wireguard.exe is like wg-quick, but it also provides the interface into the Windows network stack and the Windows DPAPI storage of your sensitive conf files. You can't even run wg set without it, because wireguard.exe is even responsible for creating the IPC Server that interfaces with WinTun.
First post ever on this platform. Wanted to jump on here and ask about my setup. I have a Pfsense firewall running wireguard. I have the typical setup for a full tunnel configured in both pfsense and the client devices alike. When I access the internet everything works just fine. I have my firewall rules set so that I'm able to access various subnets and interfaces. However, I have a windows 11 pc on lets say interface 1 @ 10.x.x.x and a gateway @ 10.x.x.1. When I activate the wireguard tunnel I can ping the gateway (10.x.x.1) just fine. When I go to ping the windows host at 10.x.x.x I'm unable to do so. I'm unable to access this machine and want to be able to access my portainer instance outside of the house. I would switch to proxmox and or linux to run this but I do also want to use this server in particular for extra development work and as a remote gaming machine.
The things I've tried. First off I tested on my interface 2 @ 172.x.x.x and was able to ping the windows 11 machine successfully after setting up a firewall rule in advanced windows defender network settings and now can tell my pfsense firewall rules are working and that I'm able to establish a connection with this machine. I also tested out accessing portainer at its address and port. This is great .... when I'm home. The other issue I tried to rule out is the firewall settings. I have a interface 3 @ 100.x.x.x which is wireguards interface. I have the same rules for both interface 2 and interface 3 basically just a rule that allows interface 2 and 3 respectively to access interface 1. Completely lost and have a feeling this is a win11 issue.
Does anyone know why this might be happening? Do I need to setup a rule for the wireguard interface (theres an interface directly labeled wireguard in pfsense)? Is it a windows firewall issue that I haven't ever heard of?
Hi friends, I cannot give up on the idea that wireguard cannot work on windows 7 x64, I use a GL.inet AR750S ext device in cascade to my vodafone station router. with OpenWrt firmware 18.06.1. The configuration of my WG server is as follows:
opewrt config668604 43.1 KB
I can't understand why once the wireguard network is activated on my client shortly after a few minutes the network goes into lockout, the only way to restart it is to DISABLE and REACTIVATE the wireguard network.
Is the AR950S acting a a 'server' to which the windows system is connecting as a 'client' (so for example, the AR950S at home, windows system in some other location connecting back to your AR950S via wireguard)?
On the GL.inet AR750S EXT device. the server configuration file is located on / etc / config / wireguard_server. The firmware that I use is the latest version available from the owner, having this router cascaded to the vodafone station router I can't do otherwise.
I am writing an application in Go that will use WireGuard tunnels to communicate. I want to embed WireGuard within the application rather than install the separate WireGuard program. I understand that I can use wireguard.dll and tunnel.dll to embed in a general application. But given my app is also written in Go, is this still the right way to go? Or should I be calling go libraries from within the WireGuard-Windows program instead?
Since WireGuard requires a driver to be installed, and this generally requires a valid Microsoft signature, you may benefit from first installing a release of WireGuard for Windows from the official wireguard.com builds, which bundles a Microsoft-signed driver, and then subsequently run your own wireguard.exe. Alternatively, you can craft your own installer using the quickinstall.bat script.
This tutorial goes through the process of setting up a Wireguard server on Windows. Most Wireguard tutorials on the internet only give you the choice of hosting a server in a Linux environment. However, it is very possible to setup a windows server.
After searching for a tutorial to no avail, I spent a couple days to figure out the best way to do it and how to automate the process. Ideally you would still want to run it in an Linux environment, but if you have a use case for a windows server like me, you would appreciate just how flexible Wireguard is!
After you prepared the server config files, place it in a folder somewhere permanent.
For this tutorial I will assume the server config file is placed at C:\wireguard\wg_server.conf
You will only need to run the command once, wireguard's background service will remember the run state over reboots.
Once you start the server, wireguard will create a new network adapter as the same name as your server config file. Thus for our tutorial, the network adapter name would be "wg_server"
Check if the network adapter is successfully created.
Step 2.1: (Optional) Setting adapter profile
Now we have the wireguard adpater setup, it is recommended to change it to "Private" profile", by defaults the adapter is added as "Public". Private profile will allow greater compatibility for the clients (say you want to use some remote desktop etc). Public profile may block these ports and services.
Now that server is running, the client should be able to handshake (given that you have the correct ports open and forwarded correctly).
However, you will notice the client won't be able to access either the internet or the LAN network.
This is because by default windows do not bridge or NAT the wireguard interface with your actual physical internet interface.
In Linux this is done by some PostUp/PostDown firewall commands, which we do not use here.
Instead, we use a powershell script to enable the NAT (or in Windows term "internet sharing") function:
Technically you can do this through the windows gui using the properties menu manually, but having this script will allow you to automate the server start/stop process as you will see later on in the tutorial.
By default, when internet sharing (NAT) is enabled, Windows will change the IP address of the adapter to something else (to avoid conflicts). However, we already know what ip address we want to adapter to be (set in the [interface] block in our wireguard config), which is 192.168.200.1 in our case.
To modify the default IP Windows will switch to, we can simply change the setting in registry.
Open Registry Editor and go to the following path:
Since there is a windows bug that internet connection sharing will not auto start on reboot, we need to change a few settings to make sure internet sharing is started. The earlier tutorial used a scheduled task to accomplish this, but I've found a better way after reading the windows bug fix here.
Compared to Linux, setting up a windows wireguard server can be tricky.
However, I have done most of the ground work for you (the powershell script to enable NAT).
Running the powershell script on startup with 3 minutes delay is not elegant, but it works.
There should be a way to run the task after the wireguard service is started and running, but I wasn't able to get it to work. If you know how to get it to work, please share it with me.
My company is setting up a frontend for an HVAC network. We have been given our own VLAN for our equipment, but the client does not want the web server on their network and will not allow any incoming connections. My boss has been working with there IT for a while trying to com up with a solution. I figured I would try to come up with my own solution to help out and if I got something working I would show him. So I started messing with wireguard. I set up a test network that mimics how the network will be set up.
