Hi, I am setting up an internet gateway that runs e2guardian with sslmitm mode enabled. What I want to do is setup the gateway machine to transparently redirect HTTP and HTTPS requests to the instance of e2guardian running on port `8080`. Mitmproxy would be the entity that does the redirection, hence the mixing transparent and upstream mode. I have been using iptables nat’ing rules to catch all port `80` and `443` traffic and redirect it to `127.0.0.1:1234` on the gateway machine where mitmproxy is listening, mitmproxy however can only forward **or** intercept but not both. Is what I am trying to do even possible using mitmproxy? Finally, not trying to sound harsh, but to anyone who thinks this can’t be done at all, please take a look at [proxy.py](https://github.com/robotman3000/proxil/blob/master/src/proxy.py). This is code I wrote (heavily modified really) as a proof of concept test. Thanks

If I understand you correctly, you are just looking for a tool that transparently wraps connections and tunnels them through an HTTP proxy. There are a few dedicated tools to do this, e.g. redsocks - how about using one of those?

You have understood me correctly, and actually I had already found redsocks but I couldn’t manage to get it working. It would always accept my connection but then never complete and eventually the connection would timeout. I found one or two other programs that seemed to be able to do HTTP CONNECT tunneling but I was not able to get them working either. Could you please give me a list of the tools you are aware of?
