sudo dnf install wireguard-tools

For Arch Linux, you can sprinted pacman to receive the Wireguard core tools:

sudo pacman -S wireguard-tools

Attest that you’ve totally ranked the Wireguard tools by filling its suggestions orchestrate:

wg -h

Position Up the Wireguard Server

Assumption: This article assumes that you’re installing the Wireguard server on a Linux mechanism through a publicly accessible IPv4 address. The instructions will still job on a server behind a NAT, yet it won’t situate nodes exterior its subnet.

Position the network interface that owns availability to the internet gaining gain use of of the ip command:

ip route get 8.8.8.8

Stashed the merit of the -o flag on both PostUp as well as PostDown variables to the interface through internet availability, then conserve your config document.

Amenable the server’s “/as well as so on/sysctl.conf” document gaining gain use of of your favorite text editor:

sudo nano /etc/wireguard/wg1.conf

Scroll down to the [Peer] liberty, then fluctuation the PublicKey variable through your 2nd patient’s public pivot.

Preserve your config document, then start the 2nd VPN interface gaining gain use of of the wg-speedy command:

sudo wg-quick up wg1

Attest that your initially as well as 2nd Wireguard clientele are mirroring up properly on your server by rushing wg.

Expurgating the Wireguard Network

Wearing both your server as well as clientele on the Wireguard network, you can currently check-up the connectivity as well as latency in between your nodes. To do this, gain sure that you have network diagnostics tools ranked on your mechanism:
