WireGuard installer

This project is a bash script that aims to setup a WireGuard VPN on a Linux server, as easily as possible!

WireGuard is a point-to-point VPN that can be used in different ways. Here, we mean a VPN as in: the client will forward all its traffic trough an encrypted tunnel to the server. The server will apply NAT to the client's traffic so it will appear as if the client is browsing the web with the server's IP.

The script supports both IPv4 and IPv6. Please check the issues for ongoing development, bugs and planned features!

WireGuard does not fit your environment? Check out openvpn-install.

Requirements

Supported distributions:

• Ubuntu >= 16.04
• Debian 10
• Fedora
• CentOS
• Arch Linux

Usage

Download and execute the script. Answer the questions asked by the script and it will take care of the rest.

curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
chmod +x wireguard-install.sh
./wireguard-install.sh

It will install WireGuard (kernel module and tools) on the server, configure it, create a systemd service and a client configuration file.

Run the script again to add or remove clients!

Configure clients

RHEL 8

Install the necessary packages:

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
sudo dnf install dnf-plugins-core
sudo dnf config-manager --enable elrepo
sudo dnf install kmod-wireguard wireguard-tools

Create file /etc/wireguard/wg0.conf with contents of the client config generated by the script (copy paste from server).

Connect:

systemctl start wg-quick@wg0.service

Verify your public has changed to server's IP, e.g.: curl https://ident.me
