Module tcp 

TCP stream proxy service

Implements raw TCP proxying with a standalone serve() method. Provides bidirectional tunneling between clients and backends.

Optionally terminates TLS at the proxy (driven by the endpoint’s stream.tls config) and/or prepends a PROXY protocol v2 header to the upstream connection (driven by stream.proxy_protocol).
