: VPS-MX introduces negligible performance overhead while drastically reducing deployment time and human error. 4.3 Scalability Test VPS-MX was used to generate 50 client certificates and corresponding .ovpn files. The script completed the batch in 14 seconds. Manual generation using Easy-RSA would take ~10 minutes. The OpenVPN server handled 50 concurrent clients with <5% CPU usage. 5. Practical Use Cases 5.1 Personal Privacy Gateway A user deploys VPS-MX on a $5/mo VPS, selects WireGuard, and connects their phone/laptop. The script auto-generates QR codes for WireGuard mobile clients. 5.2 Small Office VPN A business installs OpenVPN with user expiration dates (e.g., for contractors). The admin panel (optional) allows disabling access without SSH. 5.3 Bypassing Censorship In regions with heavy firewall restrictions, VPS-MX can deploy Shadowsocks + V2Ray + WebSocket + TLS over port 443, mimicking HTTPS traffic. The script includes domain fronting and CDN support. 5.4 Gaming Tunnel Using badvpn-udpgw (included), users can reduce packet loss for UDP-based games. VPS-MX sets up port forwarding and bandwidth limiting per user. 6.

Author: Technical Research Division, Network Automation Studies Publication Date: April 2026 Abstract The increasing demand for secure remote access and privacy protection has led to the widespread adoption of Virtual Private Networks (VPNs). However, manual configuration of VPN servers on Linux-based Virtual Private Servers (VPS) is error-prone, time-consuming, and requires deep networking expertise. The VPS-MX Script (also known as vps-mx ) has emerged as a community-driven Bash automation framework that simplifies the deployment of OpenVPN, WireGuard, SSH tunnels, and proxy services. This paper provides a comprehensive analysis of VPS-MX, including its architecture, core components, security implications, performance characteristics, and practical use cases. Empirical tests show that VPS-MX reduces deployment time from ~45 minutes (manual) to under 2 minutes while maintaining comparable security postures. We conclude with best practices and recommendations for secure adoption.
