Wireguard docker server

WireGuard is a simple, fast, and secure VPN that utilizes state-of-the-art cryptography. WireGuard is still under development, but even in its unoptimized state it is faster than the popular OpenVPN protocol. A connection is established by an exchange of public keys between server and client.

Only a client that has its public key in its corresponding server configuration file is allowed to connect. WireGuard sets up standard network interfaces such as wg0 and wg1which behave much like the commonly found eth0 interface. This makes it possible to configure and manage WireGuard interfaces using standard tools such as ifconfig and ip. This guide will configure a simple peer connection between a Linode running Ubuntu The client can be either your local computer or another Linode.

Add the Wireguard repository to your sources list. Apt will then automatically update the package cache. DKMS will then build the Wireguard kernel module.

This will save both the private and public keys to your home directory; they can be viewed with cat privatekey and cat publickey respectively. Each peer in the VPN network should have a unique value for this field.

PostUp and PostDown defines steps to be run after the interface is turned on or off, respectively. The rules will then be cleared once the tunnel is down.

SaveConfig tells the configuration file to automatically update whenever a new peer is added while the service is running. The process for setting up a client is similar to setting up the server. If your client uses Ubuntu, follow the steps provided in the above sections and in this section. For installation instructions on other operating systems, see the WireGuard docs. There are two ways to add peer information to WireGuard; this guide will demonstrate both methods. The second way of adding peer information is using the command line.

Run the following command from the server. Replace the example IP addresses with those of the client:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

You signed in with another tab or window.A VPN is a virtual private network between a device in front of you and a server in a data center. If you want to hide your internet traffic from other people on your local network, you can create a tunnel between your device and a server.

All your network traffic will go through this connection, and traffic is usually encrypted from one end to the other. And yet, it also means that the person who operates the server can see all unencrypted traffic.

Many VPN companies analyze your browsing habits, sell them to advertisers, inject their own ads on non-secure pages, steal your identity, log your internet traffic, share information with law enforcement and more. There are multiple ways to create a point-to-point VPN tunnel. Your device and the server need to use the same protocol to talk to one another.

The most popular protocol is OpenVPN. IPsec, combined with IKEv2 authentication, is another popular protocol. It seems like there are plenty of options already. But OpenVPN has been around for 17 years. It is slow and it was never designed for mobile devices. WireGuard creator Jason Donenfeld only wrote 4, lines of code for the initial release.

You generate a set of public and private keys and exchange public keys with the server. WireGuard is still quite new and experimental.

There are also very few WireGuard implementations with a graphical user interface. Once the setup is done, you should have a new folder on your hard drive with everything you need to connect to your VPN server.

Conceptual Overview

The easiest way to use WireGuard is to install the Android app and add the. On your Mac, you need to install WireGuard using Homebrew brew install wireguard-tools. You can then move the myvpnserver. I wanted to go one step further and skip the Terminal window.

On macOS, you can create an AppleScript using the Script Editor app and put it in your menu bar by enabling the menu bar option in the settings. In my script, I also fetch my current hostname using icanhazptr. There you have it. This setup offers the same convenience but with a more stable VPN connection. Once again, WireGuard is experimental. You need to assess your risks before using WireGuard at a production level. You also need to be comfortable with a buggy implementation.

But the fact that you can close your laptop, switch to another Wi-Fi network and stay connected to the VPN server is pretty neat.It aims to be fastersimplerleaner, and more useful than IPsec, while avoiding the massive headache.

It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.

If you'd like a general conceptual overview of what WireGuard is about, read onward here. You then may progress to installation and reading the quickstart instructions on how to use it.

If you're interested in the internal inner workings, you might be interested in the brief summary of the protocolor go more in depth by reading the technical whitepaperwhich goes into more detail on the protocol, cryptography, and fundamentals. If you intend to implement WireGuard for a new platform, please read the cross-platform notes. You add a WireGuard interface, configure it with your private key and your peers' public keys, and then you send packets across it. All issues of key distribution and pushed configurations are out of scope of WireGuard; these are issues much better left for other layers, lest we end up with the bloat of IKE or OpenVPN.

In contrast, it more mimics the model of SSH and Mosh; both parties have each other's public keys, and then they're simply able to begin exchanging packets through the interface.

WireGuard works by adding a network interface or multiplelike eth0 or wlan0called wg0 or wg1wg2wg3etc. This network interface can then be configured normally using ifconfig 8 or ip-address 8with routes for it added and removed using route 8 or ip-route 8and so on with all the ordinary networking utilities.

The specific WireGuard aspects of the interface are configured using the wg 8 tool. This interface acts as a tunnel interface. WireGuard associates tunnel IP addresses with public keys and remote endpoints. When the interface sends a packet to a peer, it does the following:.

Behind the scenes there is much happening to provide proper privacy, authenticity, and perfect forward secrecy, using state-of-the-art cryptography. At the heart of WireGuard is a concept called Cryptokey Routingwhich works by associating public keys with a list of tunnel IP addresses that are allowed inside the tunnel.

Each network interface has a private key and a list of peers. Each peer has a public key. Public keys are short and simple, and are used by peers to authenticate each other. They can be passed around for use in configuration files by any out-of-band method, similar to how one might send their SSH public key to a friend for access to a shell server.

In the server configuration, each peer a client will be able to send packets to the network interface with a source IP matching his corresponding list of allowed IPs. For example, when a packet is received by the server from peer gN65BkIK In the server configuration, when the network interface wants to send a packet to a peer a clientit looks at that packet's destination IP and compares it to each peer's list of allowed IPs to see which peer to send it to.

For example, if the network interface is asked to send a packet with a destination IP of In the client configuration, its single peer the server will be able to send packets to the network interface with any source IP since 0.Friday, 1st of November, A.

For a moderately security conscious geek like myself, there can be a number of reasons to want to set up a home VPN server:. I have use cases for all of those from time to time, and after a bunch of frustrated attempts at getting OpenVPN working as I want it to, I decided to try Wireguarda fairly new VPN software that promises to cut through some of the complexities of OpenVPN or IPSec, while delivering a secure and fast connection.

How I made my own WireGuard VPN server

The official Wireguard installation page has instructions for lots of different platforms. Run wg genkey on the Wireguard server, and copy it so we can use it for the server configuration file. As the name implies, the private key should be kept private to ensure the security of the VPN connection. Here, we use The macOS client fills out the PrivateKey field when creating a new tunnel. It should not be the same as the private key used in the server configuration.

Copy the generated public key again, the macOS client generates it automatically for us so we can put it in to the server configuration. That is a reasonable configuration, in my opinion. When that is done, check the server status by running sudo wg. That should output something like this:. Go edit the tunnel we created earlier, and change the configuration to something like this leaving the private key we set up earlier alone, so it matches the public key in the server config :.

There are a few important thing to keep note of here, when adopting this configuration for your own use:. Here we use 0. That is what you need for reasons described in the motivation section. If you just want to access your home LAN through the VPN, and use your regular network connection for everything else, fill in its network instead, e. Endpoint is the hostname or IP address plus port number where the Wireguard server can be reached. If the line is not present already, add it.

For IPv6 routing, also set net. On Raspbian, this is done by running:. Once that is done, try rebooting to see if everything loads correctly and ensure the IP forwarding we enabled is loaded correctly. After rebooting, running sudo wg should give you the same output as before, indicating that the Wireguard server is running as expected.

If all goes well, you should see the information change to indicate data flowing through the VPN connection, like this:. If you connect to the server and run sudo wgyou should see something like this:. I wrote this after having the friendly people in the wireguard channel on Freenode IRC help me understand Wireguard better.

Accessing servers with IP white lists common case for security hardened IT systems.I am, of course, talking about WireGuard.

What does that mean for you? It's fast. Let's begin! Install it:. In the tunnel VPN configuration, give the tunnel a name. Also specify your dynamic DNS name in the local endpoint section and generate your keys:. The purpose of this local endpoint information is to tell your client how to find your WireGuard VPN server in the vast world of the internet.

In my case, this blog is self-hosted that is, this blog's web server sits on the same network as my unRAID server in my homelab and therefore I will use my URL as the local endpoint. Also take note of the port specified typicallywe'll need it to set up port forwarding on the firewall.

This will vary from router-to-router. I use pfSense which leads to the simple rule shown below:. All routers will have this ability typically under advanced configurationbut if you need help with this step, let me know in the comments below and I'll do my best to help you out.

Activate your WireGuard server and set it so that it automatically starts on boot up:. Set peer type to "Remote Tunneled Access". Click apply:. Note: I am making a judgement call here with the "peer type of access" to use. My recommendation of "Remote tunneled access" does two things for us that I think most users will want:.

This will present you with the configuration for your client. Click download:. To be able to use this configuration file, you'll need to download the WireGuard client available here install it :. If you are running a Pi-hole docker container on unRAID, keep reading for the special set up below that will allow you to keep using your Pi-hole docker container.

Again, all of this is optional. If you do, you'll likely run into a problem with DNS resolution at this point. This may be a bit of an oversimplification since I think when you use the "custom" network type in the Docker container, you're actually using an ipvlan network, but the end result is apparently the same. The way around this is would be to either move to another interface or set up a router-on-a-stick with VLANs.

However, I recognize that this isn't necessarily the most practical solution. VLANs carry a lot of overhead in the sense that your network has to be set up for them. And you don't necessarily have a second NIC for the alternative interface option. In that spirit, I have found a way around having to do either, instead I'll have you first move your unRAID webGUI port off port 80 to a new port and subsequently switch your Pi-hole Docker container over to the host network.

Detailed instructions below! For those of you who don't have a homelab exotic enough to have VLANs and who also don't have a spare NIC lying around, I have come up with a solution to make the Docker Pi-Hole container continue to function if you are using WireGuard.

Take your Pi-hole container and edit it.You'll first want to make sure you have a decent grasp of the conceptual overviewand then install WireGuard. After that, read onwards here. Before explaining the actual comands in detail, it may be extremely instructive to first watch them being used by two peers being configured side by side:. A new interface can be added via ip-link 8which should automatically handle module loading:.

An IP address and peer can be assigned with ifconfig 8 or ip-address 8. The interface can be configured with keys and peer endpoints with the included wg 8 utility:. Finally, the interface can then be activated with ifconfig 8 or ip-link 8 :.

There are also the wg show and wg showconf commands, for viewing the current configuration. Calling wg with no arguments defaults to calling wg show on all WireGuard interfaces. Consult the man page of wg 8 for more information. Much of the routine bring-up and tear-down dance of wg 8 and ip 8 can be automated by the included wg-quick 8 tool :.

WireGuard requires baseencoded public and private keys. These can be generated using the wg 8 utility:. This will read privatekey from stdin and write the corresponding public key to publickey on stdout.

By default, WireGuard tries to be as silent as possible when not being used; it is not a chatty protocol. For the most part, it only transmits data when a peer wishes to send packets. When it's not being asked to send packets, it stops sending packets until it is asked again. In the majority of configurations, this works well. However, when a peer is behind NAT or a firewall, it might wish to be able to receive incoming packets even when it is not sending any packets. This is called persistent keepalives.

When this option is enabled, a keepalive packet is sent to the server endpoint once every interval seconds. A sensible interval that works with a wide variety of firewalls is 25 seconds. Setting it to 0 turns the feature off, which is the default, since most users will not need this, and it makes WireGuard slightly more chatty.

If you don't need this feature, don't enable it. But if you're behind NAT or a firewall and you want to receive incoming connections long after network traffic has gone silent, this option will keep the "connection" open in the eyes of NAT. This will automatically setup interface wg0through a very insecure transport that is only suitable for demonstration purposes.

You can then try loading the hidden website or sending pings:.

By connecting to this server, you acknowledge that you will not use it for any abusive or illegal purposes and that your traffic may be monitored. If you're using the Linux kernel module and your kernel supports dynamic debugging, you can get useful runtime output by enabling dynamic debug for the module:.
