Nginx TCP/UDP Load Balancer

[Dr_tux]

When I add the proxy_bind parameter, requests are never forwarded to the
server behind. If I do not add it, the output on the turn server is as
follows.

Output: 
96: handle_udp_packet: New UDP endpoint: local addr Turn_Server_IP:3478,
remote addr NGINX_IP:59902

stream {

    upstream stream_backend {
	server Turn_Server_IP:3478;
    }

    server {
    listen        3478 udp;
    proxy_pass    stream_backend;
    proxy_bind $remote_addr transparent;
    }

}

Thanks for help.
