Setup IPsec VPN

setup-ipsec-vpn is a set of automated scripts that allow you to deploy your own IPsec VPN server on Linux in just a few minutes. It supports multiple VPN protocols, including IPsec/L2TP, Cisco IPsec (XAuth), and IKEv2, providing strong encryption to protect network traffic. By encrypting all traffic between the client and server, the VPN prevents eavesdropping on unsecured networks such as public Wi-Fi in coffee shops, hotels, or airports. The project uses Libreswan as the IPsec server and xl2tpd as the L2TP provider, with additional options to install WireGuard or OpenVPN on the same host. It is designed for simplicity—requiring only a single command to set up, with randomly generated secure credentials created during installation. The repository also provides helper scripts for user and certificate management, client configuration files for major platforms, and support for deploying on popular Linux distributions and public cloud services.
