**Update**
I have noticed that after upgrading Ubuntu to 20.04 or 22.04 I have run into a little snag. It appears that the upgrade over rights the sysctl.conf file back to default values. The symptom is your wiregurad server will not be forwarded IP V4 or V6 traffic.
To resolve the issue perform the following steps.
- sudo nano /etc/sysctl.conf
- net.ipv4.ip_forward = 1
- sudo sysctl -p
WireGuard is a simple, fast, and secure VPN that utilizes state-of-the-art cryptography. With a small source code footprint, it aims to be faster and leaner than other VPN protocols such as OpenVPN and IPSec. WireGuard is still under development, but even in its non optimized state it is faster than the popular OpenVPN protocol. In fact it connects so quickly you'll likely find your self going to whats my IP to insure your traffic is actually being tunneled.
The WireGuard configuration is as simple as setting up SSH. 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 wg1), which 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. I was going to post a guide but there are so many good guides already on the internet just google it. Also the official documentation is really good and has some install guides as well.
Enjoy, be safe, support and contribute to WireGuard.
