Configure WireGuard Client

Install WireGuard, the simple, fast and modern VPN software.

[1] Transfer files or notify contents of [Private key for client] and [Public key for server] generated on WireGuard server to target Client computer.

[2] Install WireGuard.

[[email protected] ~]$ sudo dnf install wireguard-tools -y

[2] The kernel modules are automatically activated when you reboot after installing WireGuard. However, we will manually enable the kernel module to be able to do the remaining settings without rebooting.

[[email protected] ~]# sudo lsmod | grep wireguard
[[email protected] ~]$ sudo modprobe wireguard
[[email protected] ~]$ sudo lsmod | grep wireguard
wireguard              94208  0
libchacha20poly1305    16384  1 wireguard

[3] Let's create the configuration file shared by the WireGuard server administrator.

[[email protected] ~]$ sudo vi /etc/wireguard/wg0.conf

Address =
PrivateKey = YADpm+xptxt0j2scg0MsoRCqJ6cdfGihe8TkILZHZ0Q=

AllowedIPs =
PersistentKeepalive = 25
Endpoint =
PublicKey = 9LiBYQIEj91kHkmM93ilCk++ZSzWLncQGNz2iwHBFyw=

[4] Let's start the WireGuard service and check that it is running.

[[email protected] ~]$ sudo systemctl start [email protected]
[[email protected] ~]$ sudo wg
