Hello,

When my application connects to a sever, I am intercepting the request and routing it to a nginx process located on the same host (listening to 127.0.0.1:8883).
The interception need to be transparent, so IP tables does that well. Now the issue is restoring the original destination. This would be trivial with HTTP, however MQTT or AMQP can also be used.

I have looked at Tproxy protocol, it looks promising, but I have not found any way to use it with Nginx. It seems it is used for IP transparency for upstream server, not for transparently intercepting client messages.

Can I still implement a transparent interception of requests with Nginx?

Thank you!
