INTANG is a Linux daemon that evades the Great Firewall of China's TCP reset attacks by desynchronizing the TCP Control Block on censorship devices using crafted insertion packets. It operates at the TCP/IP layer, protecting all TCP-based application protocols such as HTTP, DNS over TCP, OpenVPN, and Tor.

Use cases

• bypass GFW TCP reset attacks
• protect TCP connections from censorship
• evade the Great Firewall of China
• run anti-censorship tooling on a proxy server
• keep OpenVPN or Tor connections from being reset
• circumvent TCP-level internet censorship on Linux

When to choose

• you need TCP-layer censorship evasion that works for all application protocols
• you run Linux with netfilter support and root privileges
• you want to deploy protection on a proxy for other users

When to avoid

• you need a user-friendly application-layer VPN or proxy client
• you cannot run a root daemon on Linux
• you need support for non-TCP protocols only
