Wireguard config

The section headers below tells you whether the work is on the CentOS server server or the Arch Linux client client. Configure the wireguard network interface.

Here we are using the output of wg genkey directly. The PrivateKey option in the wg-quick configuration file also accepts a file path to a file containing the private key, if that should be more desirable.

Take note of the public key of the server. All of the clients will need it in order to establish a wireguard connection to this server. This example client host is running Arch Linux. If you are running CentOS on your client too, repeat the installation steps as described in the previous step instead.

The contents of private. This is a private keyhence, a secret that should not be shared with anyone. In contrast to the public key which is not considered secret and can even be sent over an unencrypted channel. The public key has to be registered on the server in a later step. Take note of how to extract it:. Create a wg-quick configuration file which makes it easier to bring up and down one or more WireGuard interfaces. Remember to add the flag --permanent when it works.

So easy to forget. Copy the public key from the client and paste it into the server configuration, like below.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Instructions Explanation of the different fields.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! Disclaimer Using Wireguard on Windows as server is not officially supported. Use at your own risk.

This step is the same as other Linux tutorials. After you prepared the server config files, place it in a folder somewhere permanent. Instead of using the GUI to start the server, we will start it using command options. At the time of this tutorial the official GUI only allows one connection at a time.

Running the server using command line options allows us the keep the GUI free for daily use. Without saying, adjust the file paths if they are different on your system. You need to run these with administrative privilege! Once you start the server, wireguard will create a new network adapter as the same name as your server config file. Step 2. Private profile will allow greater compatibility for the clients say you want to use some remote desktop etc.

Private profile may block these ports and services.

How to Setup Wireguard VPN Server On Windows

Now that server is running, the client should be able to handshake given that you have the correct ports open and forwarded correctly.

This is because by default windows do not bridge or NAT the wireguard interface with your actual physical internet interface. Note: The shell script is originally created by igoravlI made some modification to simplify the process and get rid of some errors for our wireguard server application. Save the script in the following location:. If everything goes well, when you open the properties panel of your main internet network adaptor Ethernet 3 in my case the following options should be ticked:.

Now everything should be working correctly, the client should be able to reach the internet and LAN network you allow it to.

Step 3. 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 configwhich is 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:. Disable and re-enable Internet connection sharing NAT using the powershell command in Step 3 to make sure this change takes place you might need to restart computer. 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. Step 4. 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. If you know how to get it to work, please share it with me.WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be fastersimplerleaner, and more useful than IPSec, while avoiding the massive headache.

It intends to be considerably more performant than OpenVPN. First you need to generate the privatekey and publickey. The following commands will generate two files for the key. Please use vi or "winscp" to edit these files.

You need to generate private key and public key in both Server side and Client side. From here you can search these documents.

Enter your search terms below. Toggle navigation. From firmware V2. You need to ssh to the router and do the following. Install Wireguard opkg update opkg install wireguard Configuration You can install Wireguard either as Server or client. To configure the mini router as Wireguard server or client, you need to do the following. Generate Key First you need to generate the privatekey and publickey. Restart Network Finally, restart network and firewall, or just reboot your router.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

All credit goes to the WireGuard project, zx2c4 and the open source contributors for the original software, this is my solo unofficial attempt at providing more comprehensive documentation, API references, and examples.

It shares some similarities with other modern VPN offerings like Tinc and MeshBirdnamely good cipher suites and minimal config. As of it's been merged into the 5. Whether living behind the Great Wall of China or just trying to form a network between your servers, WireGuard is a great option and serves as a "lego block" for building networks much in the same way that ZFS is a lego block for building filesystems.

But you can write your own solutions for these problems using WireGuard under the hood like AltheaNet. These are demo hostnames, domain names, IP addresses, and ranges used in the documentation and example configs. Replace them with your preferred values when doing your own setup.

Wherever you see these strings below, they're just being used as placeholder values to illustrate an example and have no special meaning.

Make sure to change the IP addresses in your configs! The blocks used in these docs are reserved for example purposes by the IETF and should never be used in real network setups. You can use any private range you want for your own setups, e. It can also optionally route traffic for more than its own address es by specifying subnet ranges in comma-separated CIDR notation.

A bounce server is not a special type of server, it's a normal peer just like all the others, the only difference is that it has a public IP and has kernel-level IP forwarding turned on which allows it to bounce traffic back down the VPN to other clients. A group of IPs separate from the public internet, e. Generally behind a NAT provided by a router, e.

Most common ones:. To people just getting started This design is nice though because it allows peers to expose multiple IPs if needed without needing multiple notations. Just know that anywhere you see something like A subnet with private IPs provided by a router standing in front of them doing Network Address Translation, individual nodes are not publicly accessible from the internet, instead the router keeps track of outgoing connections and forwards responses to the correct internal IP e.

Getting Started with WireGuard

The publicly accessible address:port for a node, e. Public relays are just normal VPN peers that are able to act as an intermediate relay server between any VPN clients behind NATs, they can forward any VPN subnet traffic they receive to the correct peer at the system level WireGuard doesn't care how this happens, it's handled by the kernel net.

If all peers are publicly accessible, you don't have to worry about special treatment to make one of them a relay server, it's only needed if you have any peers connecting from behind a NAT. In summary: only direct connections between clients should be configured, any connections that need to be bounced should not be defined as peers, as they should head to the bounce server first and be routed from there back down the vpn to the correct client. More complex topologies are definitely achievable, but these are the basic routing methods used in typical WireGuard setups:.

More specific also usually more direct routes provided by other peers will take precedence when available, otherwise traffic will fall back to the least specific route and use the WireGuard does not automatically find the fastest route or attempt to form direct connections between peers if not already defined, it just goes from the most specific route in [Peers] to least specific.

You can figure out which routing method WireGuard is using for a given address by measuring the ping times to figure out the unique length of each hop, and by inspecting the output of:.

WireGuard uses encrypted UDP packets for all traffic, it does not provide guarantees around packet delivery or ordering, as that is handled by TCP connections within the encrypted tunnel.

WireGuard claims faster performance than most other competing VPN solutions, though the exact numbers are sometimes debated and may depend on whether hardware-level acceleration is available for certain cryptographic ciphers. WireGuard's performance gains are achieved by handling routing at the kernel level, and by using modern cipher suites running on all cores to encrypt traffic. WireGuard's cryptography is essentially an instantiation of Trevor Perrin's Noise framework.

It's modern and, again, simple. Every other VPN option is a mess of negotiation and handshaking and complicated state machines. It is basically the qmail of VPN software.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It follows the Unix Philosophy closely in that it only does one thing creating secured VPN tunnels and does it well. WireGuard is changing all that by simplifying the process of getting up and running in no time and allowing for easy configuration to connect multiple clients peers.

This post is pretty verbose! If you have an AWS account you can launch a new instance by going to:. If your server is using a different distro then look at the WireGuard installation instructions.

Run wg to check if installation was successful which should not output anything if everything is OK:. Set the directory user mask to by running umask Use the wg genkey command to generate a private key. We can generate both the private and public key at once by piping the private key output to tee to save it to file but also to forward the private key to wg publickey which derived the public key from a private key and the save it to a file.

Outputting the contents of the private key file shows us the random key it generated in base64 format:. The address If your server is using that IP range already, then pick a different address like The [Interface] section is for configuration the new WireGuard interface we are creating. Make sure to enable the port for UDP traffic. Now add forwarding rules for forwarding in the server configuration file using the PostUp and PostDown config settings where PostUp value command is ran when the WireGuard service starts and PostDown value command runs when the service is shutting down.

Since we need to pass on packets from one interface to another then we need to allow IP forwarding. Allow forwarding of IP packets by uncommenting out the line net. The server is almost fully configured. Jump back to your client machine and install WireGuard. My client machine is running Arch linux but the process will be the same for most linux distros. Generate a private and public key pair for the client using the same command as we did on the server:.

The next step is to set information about the server in the client configuration file under the [Peer] section:. If your server is an EC2 instance, you get query the metadata endpoint to get the public IP address:. Go back into the server and edit the config. Now that the server has the client peer information we can start the WireGuard service with wg-quick up wg0 on the server:.

Depending on your Ubuntu installation, you might need to install additional kernel modules. Check the status by running systemctl status wg-quick wg0. Running the command ifconfig shows the new network interface wg0 with the internal IP address we specified Start the WireGuard service using wg-quick just like we did previously on the server:.

Now that WireGuard is running, check the public IP address again of the client and it should now be the public IP address of the server:.

wireguard config

The same steps will need to be followed from when we setup the first client. Instead we can generate the keys and configuration on the server and then securely transfer the information into the WireGuard app. Run wg genkey but specify different filenames this time to distinguish them from the server keys:. Create a new configuration file for the iPhone client on the server. Paste client configuration but remember to use a different private IP that differs from the first client.

Install qrencode on the server to generate a QRCode from the configuration file.
