Why is WireGuard faster than OpenVPN?

WireGuard runs directly inside the Linux kernel space using modern ChaCha20-Poly1305 cryptography, avoiding context switches between user-space and kernel-space. OpenVPN operates in user-space with OpenSSL, incurring higher CPU overhead and latency.

Can I route full PC/Mac device traffic through a single XProxy modem via WireGuard?

Yes. XProxy generates a dedicated WireGuard configuration file (.conf) for every 4G/5G modem. When imported into the official WireGuard client, 100% of system TCP, UDP, and ICMP traffic routes through that cellular modem.

Layer 3 VPN Comparison

OpenVPN vs WireGuard: Mobile Proxy Benchmark

When system-wide OS network routing is required rather than browser-level proxying, Layer 3 VPN tunnels capture 100% of network traffic automatically. Here is how OpenVPN and WireGuard compare on XProxy cellular hardware nodes.

Why Layer 3 VPN Tunnels Differ from Proxies

Unlike SOCKS5 or HTTP proxies which rely on application-level support (e.g. browser settings), OpenVPN and WireGuard create virtual network interfaces (TUN) at the operating system level.

Full OS Packet Routing: 100% of TCP, UDP, ICMP (Ping), and DNS queries route through the cellular modem automatically.
Zero Application Friction: Desktop software, Discord, online games, and terminal scripts work immediately without proxy configuration.
Single System Interface vs Multi-Profile Isolation: VPNs route 100% of OS traffic through a single interface/modem at a time. For multi-accounting with 50+ concurrent browser profiles across 50 different IPs, use SOCKS5 or VLESS proxies instead.

WireGuard vs OpenVPN Technical Matrix

WireGuard (Recommended)

Kernel Space: Executes directly inside Linux kernel space (~4,000 lines of clean code).
Modern Crypto: Powered by ChaCha20-Poly1305 and Noise protocol handshake.
Throughput: Up to 3x higher throughput with <10% CPU overhead.
Handshake: Instant connection establishing in <100ms.

OpenVPN (Legacy Enterprise)

User Space: Operates in user space with OpenSSL stack (~100,000 lines of code).
Legacy Crypto: AES-256-GCM / OpenSSL cipher suite options.
Performance: Higher CPU overhead on multi-modem hardware servers.
Use Case: Ideal for legacy enterprise firewalls requiring TLS auth certificates.

How It Works: Hardware Routing & Per-SIM Modem Protocols

XProxy provisions dedicated protocol endpoints per 4G/5G SIM modem interface out-of-the-box. Each modem plugged into XProxy gets its own isolated WireGuard TUN file, OpenVPN profile, and SOCKS5/VLESS endpoints, ensuring clean IP isolation per modem.
