Documentation

Overview

Package rtcp implements remote TCP port forwarding.

Usage:

-listen rtcp://:REMOTE_PORT/LOCAL_HOST:LOCAL_PORT -forward ssh://user:pass@server:22

Asks the last hop in the proxy chain to listen on REMOTE_PORT, and forwards each incoming remote connection to LOCAL_HOST:LOCAL_PORT locally.

The last hop in the forward chain MUST support remote listening (e.g. ssh, socks5 with BIND). Protocols like ss, vmess, trojan, http proxy do NOT support this — an error is shown.
