Some Linux distributions include support for Wireguard via Network Manager, making it very easy to set a connection without using the terminal. First check if your Linux distro supports it. The following guide has been created on Manjaro Linux running KDE Plasma.

1. Generate the .conf file using the WG Manager Tool
2. Open the Network Connections (right click on the networking icon > Configure Network Connections…), Add new connection and scroll down to select WireGuard from the list of connection types

1. Add the corresponding values from the .conf server profile generated earlier into the Network Manager Wireguard configuration

Connection name: a short name such as ‘wgno1’ – this will be the WG interface name.

1. In WireGuard Interface tab, add your private key from the .conf file. Use any port as source, in our example we will use 51821. Set the MTU to 1420

1. Open Peers… to add the server info:

Public key: the server public key from the .conf file (it is a unique value for each server)
Allowed IPs: 0.0.0.0/0, ::/0
Endpoint address: the server hostname from the .conf file
Endpoint port: any port from 51820 to 51900

1. Open the IPv4 tab and add the following:

Method: Manual
DNS Servers: 10.11.0.1
Address: your IPv4 address from the .conf file (10.11.x.y), Netmask 255.255.0.0 and gateway 0.0.0.0

Apply the settings and connect by right-clicking on the new connection from the Connections list > Connect. Check connectivity and run the test at https://ipx.ac/run to make sure that it is working properly.
