# WireGuard installer
|
||||
|
||||
|
||||
|
||||
|

**This project is a bash script that aims to setup a [WireGuard](https://www.wireguard.com/) 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.

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

To generate more client files, run the following:

Run the script again to add or remove clients!
