You might have noticed the buzz around WireGuard lately. Since the initial conditions at the creation of the universe set things up so WireGuard would eventually be underdocumented, I am going against Creation itself and showing you how to easily configure and run it.
At its core, all WireGuard does is create an interface from one computer to another. It just connects two computers, directly, quickly and securely. Luckily, WireGuard comes with a helper script, wg-quickwhich will do pretty much everything the average user needs. To install WireGuard, see the installation page, it should be a pretty simple process.
This will generate two files, privatekey and publickey on each of the computers. The publickey file is for telling the world, the privatekey file is secret and should stay on the computer it was generated on. If you just want a single connection between two computers say, to connect your laptop to your home serverthe configuration is pretty simple. On the server, enter the following:. As you can see, the addresses I picked for each computer are After writing the two files, run wg-quick up wg0 on the server and then on the client.
To close the connection again, just run wg-quick down wg0.
This assumes that your LAN interface is called eth0. For example, if your subnet is Then run wg-quick up wg0 as above, and you should be able to ping the other computers in the LAN from the client, as if you were home.
Try ping To forward all the traffic through, simply change the AllowedIPs line on the client to this:. This will make the wg0 interface responsible for routing all IP addresses hence the 0. I hope this has been useful! As always, tweet or toot any comments to me, or leave a comment below.

I was typing on my phone at lunch stuff I'd just learned this morning which referenced this article saying running a log-less Wireguard might not be possible. That means we would have to register every active device of our customers and assign the static IP addresses on each of our VPN servers.
Namely the issues around DynamicIPs. I run Wireguard on my systems and to my knowledge it does not log anything on my Linux systems not that I intended specifically to set it up that way, it is just something that I noticed. Can you tell me where I can find these logs which I am seemingly unaware of? I do know that my iOS app logs things but I'm talking about Linux. This is a really bizarre misunderstanding of the events. Wireguard does not generate any log entries by default.
Your statement is vacant without an explanation of what kind of logging Wireguard requires. Currently, all it does is attempt to scare the user with the word "rootkit". But the parent post is wrong, the defensive rootkit is not to prevent loggingit's to prevent extracting the configuration from the kernel.
It effectively makes the WireGuard configuration write-only from the perspective of userspace. WireGuard does not do any access logging by default as far as I am aware.

These logs can provide valuable information like source and destination IP addresses, port numbers, and protocols. By default, the log file is disabled, which means that no information is written to the log file.
A new dialog box appears. A new window opens and from that screen choose your maximum log size, location, and whether to log only dropped packets, successful connection or both. A dropped packet is a packet that Windows Firewall has blocked. In most production environments, this log will constantly write to your hard disk, and if you change the size limit of the log file to log activity over a long period of time then it may cause a performance impact.
The log file will be created in a W3C extended log format. A single log file can contain thousands of text entries, so if you are reading them through Notepad then disable word wrapping to preserve the column formatting. If you are viewing the log file in a spreadsheet then all the fields will be logically displayed in columns for easier analysis. The Windows Firewall security log contains two sections.
The header provides static, descriptive information about the version of the log, and the fields available. The body of the log is the compiled data that is entered as a result of traffic that tries to cross the firewall. It is a dynamic list, and new entries keep appearing at the bottom of the log. The fields are written from left to right across the page. The - is used when there is no entry available for the field.
According to the Microsoft Technet documentation the header of the log file contains:. Version — Displays which version of the Windows Firewall security log is installed. Software — Displays the name of the software creating the log. Time — Indicates that all the timestamp information in the log are in local time. Fields — Displays a list of fields that are available for security log entries, if data is available. The hours are referenced in hour format.
As you notice, the log entry is indeed big and may have up to 17 pieces of information associated with each event.
However, only the first eight pieces of information are important for general analysis. If you suspect any malicious activity, then open the log file in Notepad and filter all the log entries with DROP in the action field and note whether the destination IP address ends with a number other than If you find many such entries, then take a note of the destination IP addresses of the packets.
Once you have finished troubleshooting the problem, you can disable the firewall logging.
Troubleshooting network problems can be quite daunting at times and a recommended good practice when troubleshooting Windows Firewall is to enable the native logs.
Although the Windows Firewall log file is not useful for analyzing the overall security of your network, it still remains a good practice if you want to monitor what is happening behind the scenes.

WireGuard is an easy to configure, fast, and secure open source VPN that utilizes state-of-the-art cryptography.
Security researcher and kernel developer Jason Donenfeld realized that they were slow and difficult to configure and manage properly. This made him create a new open source VPN protocol and solution which is faster, secure easier to deploy and manage.
It is still under heavy development. Apart from being a cross-platform, one of the biggest plus point for WireGuard is the ease of deployment. Look at WireGuard set up guide. You install WireGuard, generate public and private keys like SSHset up firewall rules and start the service. Now compare it to the OpenVPN set up guide.
There are way too many things to do here. Another good thing about WireGuard is that it has a lean codebase with just lines of code. It is clearly easier to debug WireGuard. Since WireGuard runs in the kernel spaceit provides secure networking at a high speed.
These are some of the reasons why WireGuard has become increasingly popular. Can I just once again state my love for it and hope it gets merged soon? This could be confusing to new Linux users. Let me explain it to you. At present, you can install WireGuard on Linux as a kernel module.
When you install WireGuard as a kernel module, you are basically modifying the Linux kernel on your own and add some code to it. Starting kernel 5. It will be included in the kernel by default. The inclusion of WireGuard in Kernel 5. WireGuard is gaining popularity for the good reasons.
I hope you have a slightly better understanding of WireGuard. Your feedback is welcome, as always.
I am an avid Linux lover and open source enthusiast.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:. Regardless of which method you choose to add peer information to WireGuard, there should be a Peer section in the output of the sudo wg command if the setup was successful.
This Peer section will be automatically added to wg0. If you would like to add this information immediately to the config file, you can run:. This indicates that you now have a private connection between the server and client. You can also ping the client from the server to verify that the connection works both ways. The process used in this guide can be extended to configure network topologies. As mentioned previously, Wireguard is an evolving technology.

Do not use WireGuard for critical applications. The project is still undergoing security testing and is likely to receive frequent critical updates in the future. The GRUB 2 kernel is required for this guide.WireGuard is a free and open-source software application and communication protocol that implements virtual private network VPN techniques to create secure point-to-point connections in routed or bridged configurations.
WireGuard aims to provide a VPN that is both simple and highly effective. In a review by Ars Technica observed that popular VPN technologies such as OpenVPN and IPsec are often complex to set up, disconnect easily in the absence of further configurationtake substantial time to negotiate reconnections, may use outdated ciphers, and have relatively massive code overandlines of code, respectively, according to Ars Technica which makes it harder to find bugs.
WireGuard's design seeks to reduce these issues, making the tunnel more secure and easier to manage by default. Ars Technica reported that in testing, stable tunnels were easy to create with WireGuard, compared to alternatives, and commented that it would be "hard to go back" to long reconnection delays, compared to WireGuard's "no nonsense" instant reconnections.
Earliest snapshots of the code base exist from June 30, As of June [update] the developers of WireGuard advise treating the code and protocol as experimental, and caution that they have not yet achieved a stable release compatible with CVE tracking of any security vulnerabilities that may be discovered. On 9 DecemberDavid Miller - primary maintainer of the Linux networking stack - accepted the WireGuard patches into the "net-next" maintainer tree, for inclusion in an upcoming kernel.
On 20 MarchDebian developers enabled the module build options for WireGuard in their kernel config for the Debian 11 version testing. From Wikipedia, the free encyclopedia. Free and open-source VPN protocol.

With wireguard-go, instead simply run:. This will create an interface and fork into the background. To run wireguard-go without forking to the background, pass -f or --foreground :. When an interface is running, you may use wg 8 to configure it, as well as the usual ip 8 and ifconfig 8 commands. Instead use the kernel module; see the installation page for instructions.
This runs on macOS using the utun driver. It does not yet support sticky sockets, and won't support fwmarks because of Darwin limitations. This runs on Windows, but you should instead use it from the more fully featured Windows appwhich uses this as a module.
