Upstream: the "transparent" parameter of proxy_bind and friends. This parameter lets binding the proxy connection to a non-local address. Upstream will see the connection as coming from that address. When used with $remote_addr, upstream will accept the connection from real client address. Example: proxy_bind $remote_addr transparent;
