Refactor script (#92) 
- cleaned some minor code
- use IPv6 if IPv4 isn't available
- add input validations, fixes #86 .
  - assign secondary DNS to primary DNS value if it's empty. Fixes #68 
- use `$SERVER_WG_IPV4` and `$SERVER_WG_IPV6` when suggesting the client IP
- save user DNS to `params` file and apply it to all clients, removing support for customizing DNS for individual clients. If this is a problem we can add again the code to allow customization but maybe use the sourced DNS as a suggestion for clients that need a different one
- add shellcheck ignores, needed for IDE that have shellcheck support
- escaped variables to `"${var}"` style
- updated README to reflect changes
- fixed the kernel mismatch issue on CentOS by updating the kernel https://github.com/angristan/wireguard-install/issues/95#issuecomment-653696198. Fedora might need this change too
- Use `firewall-cmd` only if `firewalld` is running. Fixes #95 
- Fix the client's subnet mask. Fixes #87 
- Save the client configuration in the correct `$HOME`. Fixes #96

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
  • Debian
  • Fedora
  • CentOS
  • Arch Linux

I recommend these cheap cloud providers for your VPN server:

  • Vultr: Worldwide locations, IPv6 support, starting at $3.50/month
  • PulseHeberg: France, unlimited bandwidth, starting at €3/month
  • Digital Ocean: Worldwide locations, IPv6 support, starting at $5/month

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.

Make sure you choose different IPs for you clients.

Contributions are welcome!
