Description

Contributor guide

Research direction

Research the IP TRANSPARENT socket option and how Nginx implements proxy bind. Investigate how Caddy's layer 4 module handles sockets and if there is a way to set socket options. Look at the existing codebase for similar features (e.g., PROXY protocol). Consider writing a Caddy module that sets the IP TRANSPARENT flag on upstream connections.
