3proxy

Overview

Deploy 3proxy — the tiny, fast, universal proxy server supporting HTTP(S), SOCKS4/5, port forwarding, and transparent proxying in a single ~200KB binary. Ideal for lightweight proxy setups, proxy chaining, multi-user access with traffic accounting, and scenarios where a full VPN is overkill. This skill covers installation, multi-protocol configuration, authentication, ACLs, bandwidth control, proxy chains, and production deployment.

Instructions

Step 1: Installation

From package manager:

# Ubuntu/Debian
