chmod +x ./wg-ubuntu-server-up.sh
sudo ./wg-ubuntu-server-up.sh

Supported OS

• Ubuntu 18.04
• Ubuntu 20.04
• Ubuntu 22.04
• Debian 9
• Debian 10

wg-ubuntu-server-up.sh

This script:

• Installs all necessary software on an empty Ubuntu DigitalOcean droplet (it should also work with most modern Ubuntu images)
• Configures IPv4 forwarding and iptables rules
• Sets up unbound DNS resolver
• Creates a server and clients configurations
• Installs qrencode
• Runs WireGuard

Usage

wg-ubuntu-server-up.sh [--clients=<clients_count>] [--no-reboot] [--no-unbound]

Options:

• --clients=<clients_count> how many client's configs will be created
• --no-unbound disables Unbound server installation (1.1.1.1 will be used as a default DNS for client's configs)
• --no-reboot disables rebooting at the end of the script execution

Example of usage

./wg-ubuntu-server-up.sh

./wg-ubuntu-server-up.sh --clients=10

wg-debian-server-up.sh

This script works the same way and with the same options, that wg-ubuntu-server-up.sh do.

wg-genconf.sh

This script generate server and clients configs for WireGuard.

If the public IP is not defined, then the public IP of the machine from which the script is run is used. If the number of clients is not defined, then used 10 clients.

Prerequisites

Install WireGuard if it's not installed.

Usage

./wg-genconf.sh [<number_of_clients> [<dns_ip> [<server_public_ip>]]]

Where:

• number_of_clients how many client's configs will be generated
• dns_ip the script should use this IP as a DNS address
• server_public_ip the script should use this IP as a server address

Example of usage:

./wg-genconf.sh

./wg-genconf.sh 10

./wg-genconf.sh 10 1.1.1.1

./wg-genconf.sh 10 1.1.1.1 157.245.73.253
