How do I configure tun2socks on Windows?

Paste your proxy in IP:PORT:USER:PASS format into this tool and click Generate. The tool builds the correct .bat file with all required flags. Download it, place it in the same folder as tun2socks.exe (from github.com/xjasonlyu/tun2socks), and run it as Administrator. tun2socks then creates a TUN adapter and all system traffic flows through your proxy.

What is tun2socks used for?

tun2socks routes all system traffic — not just browser traffic — through a SOCKS5 or HTTP proxy by creating a virtual TUN network adapter. This is useful when applications do not support per-app proxy settings and you need transparent, system-wide tunneling on Windows, Linux, or macOS.

What platforms support tun2socks?

The xjasonlyu/tun2socks build (the most actively maintained fork) supports Windows, Linux, and macOS. This generator produces a Windows .bat file; Linux and macOS users run the same binary directly from a shell script or systemd unit.

Do I need to supply tun2socks.exe separately?

Yes. This tool generates the .bat launch script only. Download tun2socks.exe from the official GitHub releases page at github.com/xjasonlyu/tun2socks/releases and place it in the same folder as the generated .bat file before running.

What do the constant flags do?

--dns-addresses=8.8.8.8,8.8.4.4 tells tun2socks to forward DNS queries to Google Public DNS, preventing DNS leaks. --product-mode=no disables a commercial feature flag not needed for personal use. Both defaults work for the vast majority of setups.

What are the alternatives to tun2socks?

Common alternatives include Proxifier (Windows, commercial), redsocks (Linux), and Clash (cross-platform rule-based proxy). tun2socks is open-source and operates at the kernel network layer, which gives it broader app coverage than userspace alternatives.

Summary

Paste your proxy string (IP:PORT:USER:PASS) and download a ready-to-run tun2socks .bat file for Windows — no manual editing needed.

How it works

Paste your proxy string in IP:PORT:USER:PASS format (or just IP:PORT if the proxy has no authentication).
The tool parses the four fields, validates the host and port, and builds the .bat content with the correct tun2socks flags.
The constant flags --dns-addresses=8.8.8.8,8.8.4.4 and --product-mode=no are included automatically.
Click "Copy" to copy the batch script to your clipboard, or "Download .bat" to save tun2socks.bat directly.
Place the file in the same folder as tun2socks.exe and run it as Administrator to start tunneling all traffic through your proxy.

Use cases

Routing all Windows PC traffic through a SOCKS5 or HTTP proxy when an app has no built-in proxy settings.
Setting up a transparent proxy on Windows for testing, privacy, or bypassing network restrictions.
Generating a reproducible launch script so you can switch proxies without editing .bat files by hand.
Converting a proxy list entry (IP:PORT:USER:PASS) into a working tun2socks startup file in seconds.
Automating proxy rotation by regenerating the .bat for each new session.
