WireGuard is a fast and modern VPN protocol that is gaining popularity due to its simplicity and high performance. In this tutorial, we will guide you through the process of installing WireGuard on FreeBSD Latest using the official repository.
Before installing WireGuard, make sure your FreeBSD system is up-to-date by running the following command:
sudo pkg update && sudo pkg upgrade
WireGuard is available in the official FreeBSD repository. You can install it using the pkg package manager by running the following command:
sudo pkg install wireguard
WireGuard needs to load a kernel module to function properly. To enable it, edit the /etc/rc.conf file and add the following line:
wireguard_enable="YES"
To use WireGuard, you need to generate a private key and a public key. You can do it by running the following commands:
sudo mkdir /usr/local/etc/wireguard
cd /usr/local/etc/wireguard
sudo umask 077
sudo wg genkey | tee privatekey | wg pubkey > publickey
This will create a directory /usr/local/etc/wireguard where your private key will be stored in a file named privatekey, and your public key in a file named publickey.
Now that you have generated a private and public key, you need to create a configuration file for WireGuard. In this example, we will create a file named wg0.conf with the following content:
[Interface]
PrivateKey = <contents-of-privatekey-file>
Address = 10.0.0.1/24
ListenPort = 51820
[Peer]
PublicKey = <public-key-of-client>
AllowedIPs = 10.0.0.2/32
Replace <contents-of-privatekey-file> with the contents of the privatekey file you generated earlier. Replace <public-key-of-client> with the public key of the client you want to connect to.
To start WireGuard, run the following command:
sudo service wireguard start
You can verify that WireGuard is running by checking the output of the following command:
sudo wg show
This should display the configuration of the WireGuard interface you just created.
Congratulations! You have successfully installed and configured WireGuard on your FreeBSD system. You can now use it to connect to other WireGuard-enabled devices.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
