hwdsl2/setup-ipsec-vpn

This is an automated installation script. You only need to run one command on a Linux server, and it will automatically configure an encrypted IPsec VPN server without manual network setup.

It solves the issue of insecure internet usage on public WiFi where data can be intercepted, and allows you to remotely access home computers, NAS, or company intranet resources securely as if you were on the local network.

Users with cloud servers or Raspberry Pis, those who want to protect online privacy, need remote access to home devices, and require network security but don't want to manually configure firewalls.

1. Preventing data theft when connecting to public WiFi at cafes or airports.

2. Remotely accessing your home NAS to store files while traveling.

3. Securely accessing company intranet resources without complex corporate clients.

4. Building a personal private network to navigate certain network restrictions (assess compliance yourself).

Fully automated with no input needed, generates config files for iOS and Android automatically, supports multiple Linux systems, and includes management scripts to add users or change passwords later.

Requires a Linux server (like a VPS or Raspberry Pi), basic command line operation skills (running wget and sudo commands), no programming knowledge needed, but basic server management understanding is required.
