Setting up a VPN on a VPS allows you to create a private, secure connection for browsing, bypassing geo-restrictions, or protecting your data. Here’s a quick guide:

1. WireGuard

   • Fast, modern, and lightweight.
   • Install via:

     # Ubuntu/Debian
     sudo apt update && sudo apt install wireguard
     wg-quick up wg0

   • Config file: /etc/wireguard/wg0.conf

2. OpenVPN

   • Mature and widely used.
   • Install:

     # Ubuntu/Debian
     sudo apt update && sudo apt install openvpn

   • Generate configs with easy-rsa.

3. Shadowsocks (SOCKS5 Proxy)

   • Good for bypassing censorship (e.g., Great Firewall).
   • Install:

     pip install shadowsocks
     ssserver -c /etc/shadowsocks.json -d start

4. IPSec/L2TP (for legacy devices)

   • Compatible with older systems but slower.
   • Use tools like Libreswan + xl2tpd.

Steps to Set Up a VPN on a VPS:

1. Choose a VPS Provider

   • Affordable options: DigitalOcean, Linode, Vultr, or AWS Lightsail.
   • Select a location close to your target region for better speed.

2. Connect via SSH

   ssh root@your_vps_ip

3. Install & Configure VPN

   • For WireGuard:

     curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
     chmod +x wireguard-install.sh
     ./wireguard-install.sh

   • For OpenVPN:

     wget https://raw.githubusercontent.com/angristan/openvpn-install/master/openvpn-install.sh
     chmod +x openvpn-install.sh
     ./openvpn-install.sh

4. Allow VPN Traffic in Firewall

   sudo ufw allow 51820/udp  # WireGuard port
   sudo ufw allow 1194/udp   # OpenVPN port
   sudo ufw enable

5. Connect from Your Device

   • WireGuard: Import the generated .conf file into the WireGuard app.
   • OpenVPN: Use the .ovpn file with OpenVPN clients.

Pros & Cons:

Tips:

• Use Obfsproxy or v2ray if you need to evade deep packet inspection (e.g., in restrictive countries).
• For better privacy, choose a VPS provider that accepts crypto payments (e.g., Njalla).
• Regularly update your VPN software to patch vulnerabilities.
