What is WireGuard? Why Linux Users Going Crazy Over it?

WireGuard is an easy to configure, fast, and secure open source VPN that utilizes state-of-the-art cryptography. It's aim is to provide a faster, simpler and leaner general purpose VPN that can be easily deployed on low-end devices like Raspberry Pi to high-end servers.

What is Linux WireGuard?

WireGuard is a security-focused virtual private network (VPN) known for its simplicity and ease of use. It uses proven cryptography protocols and algorithms to protect data. Originally developed for the Linux kernel, it is now deployable on Windows, macOS, BSD, iOS and Android.

Why is WireGuard so fast?

A combination of extremely high-speed cryptographic primitives and the fact that WireGuard lives inside the Linux kernel means that secure networking can be very high-speed. It is suitable for both small embedded devices like smartphones and fully loaded backbone routers.

Is WireGuard safe?

WireGuard is highly secure, but it's not designed with privacy in mind. At time of writing, the biggest privacy weakness that WireGuard has is how it assigns IP addresses. When you connect to a VPN service using OpenVPN or IKEv2, you're assigned a different IP address each time.

Is WireGuard part of the Linux kernel?

WireGuard is a fast, flexible VPN that was designed specifically for Linux implementations, but it has been a third-party addition until now. With the release of Linux 5.6 today, WireGuard is now included in the kernel by default and will make its way into the downstream distributions, as well.

How do I know if a WireGuard is running?

Once WireGuard is installed, you can check that the installation succeeded by running: wg , if you get no output it's all good. In order to check that the WireGuard kernel module has loaded you can run sudo modprobe wireguard .

How do I add a tunnel to my WireGuard?

Setting up the WireGuard App on a device

Alternatively, if you are configuring the WireGuard mobile app for iOS and Android you can take a picture of the QR code from the app. Choose "Create from QR code" and point the camera at the QR image provided by the tunnel profile in the NG Firewall administration.

Does WireGuard hide IP address?

WireGuard's IP requirements are like any other VPN protocol

WireGuard does not require any static or fixed IP address. ... Like any other VPN protocol, it is all about your configuration, and we take that seriously to get the most out of what all VPN protocols have to offer.

Which is better open VPN or WireGuard?

In terms of security, WireGuard holds an edge over OpenVPN protocol. If we compare both these protocols, OpenVPN uses secure encryption techniques. The OpenSSL library allows for a highly secure cryptographic primer.

What is better WireGuard or OpenVPN?

In speed tests run by our team and others, WireGuard normally delivers much faster speeds than OpenVPN — but this can vary by VPN provider.

Can WireGuard be blocked?

It is indeed very easy to completely block Wireguard protocol with iptables: > iptables -A FORWARD -p udp -m length --length 120 -m u32 --u32 "0 >> 22 & 0x3c @ 8 = 0x2000000" -j DROP (Yes, from prior experience of blocking TLS and OpenVPN, usually Message ID 2 is blocked instead of Message ID 1, probably for the ...

Is WireGuard better than IKEv2?

In most cases it is faster than OpenVPN. When used in its default UDP mode on a reliable network OpenVPN performs similarly to IKEv2. WireGuard® benefits from extremely high-speed cryptographic primitives and deep integration with underlying operating system kernel, so speeds are very high with low overhead.

Is NordLynx better than OpenVPN?

For the second time in this article NordLynx with WireGuard is faster than the connection without VPN. Also ping and jitter are better than with the normal connection. The VPN connection with OpenVPN is anything but slow. Nevertheless it is slower than the WireGuard connection.
