tun2socks for Windows

Overview

tun2socks is a free Windows utility that creates a virtual network interface to funnel selected traffic through a SOCKS proxy. By leveraging the gVisor TCP/IP implementation, it can intercept and reroute connections without changing the machine’s global network settings, giving users a way to control which programs use the proxy.

Key advantages

• Minimal configuration required to direct application-level traffic through a proxy.
• Uses gVisor’s TCP/IP stack for stable and predictable behavior.
• Lets you proxy individual services or apps rather than the whole system.
• Available at no cost and listed under Utilities & Tools for easy discovery.

How it functions

tun2socks sets up a virtual tunnel on Windows that captures outgoing connections and hands them to a SOCKS proxy. The gVisor stack handles the TCP/IP processing inside that tunnel, so applications continue to operate normally while their traffic is forwarded through the proxy endpoint.

Typical scenarios for use

• Redirect a single browser or game through a SOCKS proxy without touching system-wide routes.
• Protect the network traffic of a specific service while leaving other connections untouched.
• Test how an application behaves when its traffic originates from a different IP or endpoint.

Quick setup guide

1. Download and install the tun2socks package appropriate for your Windows version.
2. Configure the SOCKS proxy address and port in the tun2socks settings.
3. Specify which applications or ports should be captured by the virtual interface.
4. Start the service and confirm traffic is being forwarded through the proxy.

Performance and categorization

Listed under Utilities & Tools, tun2socks is geared toward users who want fine-grained control over network routing. Its integration with gVisor contributes to dependable operation, making it a practical choice for privacy-conscious users or administrators needing selective proxying.
