TProxy-TCP-UDP

Transparent proxy (TProxy) is a Linux technique that captures outbound connections at the system level. Because interception happens before applications are aware, no proxy address, environment variable, or browser setting is required β€” everything is simply routed.

What TProxy Delivers

  • App unawareness: Software runs normally while traffic is proxied underneath.
  • TCP plus UDP: Both stream and datagram traffic are transparently handled.
  • Low-level speed: The kernel does the work, avoiding userspace bottlenecks.
  • Part of Linux: Integrated with netfilter and policy routing.
  • Granular control: Route by IP, port, or other packet attributes.

  • port: Local port for TProxy listener
  • network: Network type (tcp or udp)
  • device: Network device to bind to
