            This is a community wiki answer. Feel free to expand it.

            As already discussed in the comments, the EnvoyFilter was not yet supported in Istio version 1.2 and actually that version is no longer in support since Dec 2019.

            I strongly recommend upgrading to the latest Istio and Envoy versions. Also, after you upgrade please notice that the filter name you want to use was deprecated and replaced. You should now use envoy.filters.network.tcp_proxy instead of envoy.tcp_proxy.

            Please remember that things are getting deprecated for a reason and keeping the old versions will sooner or later bring you more trouble. Try to keep things more up-to-date.

            More details can be found in the latest docs.

            You'll need to insert the envoy.filters.network.ext_authz filter into the filter chain before the envoy.filters.network.tcp_proxy and setup a cluster that will actually make the Authz decision.

            The envoy docs have a good example to follow.

            ISTIO Ingress Gateway logs
            Asked 2020-Aug-14 at 15:09

            We have set up Istio, and we are using ISTIO ingress gateway for inbound traffic. We have set up TLS for TCP port. Sample code can be found here.

            We also enabled logs by following this ISTIO guide

            We tested the TLS connection using openssl and it works fine.

            However, when we try to connect from an application, the TLS negotiation fails. I have provided more details with wireshark here

            We would like to get logs from ISTIO on the TLS negotiation ... and find why it fails.

            After getting the message of no matching filter chain, I found the filter chain for the port 31020 with the domain that I have provided in my Gateway config. It looks like while connecting my application(ODBC), the host was not being provided.

            The solution is simply to replace the host domain by '*'

            Why is my Python proxy not accepting connections?
            Asked 2020-Aug-02 at 02:15

            I am trying to develop a TCP proxy library using Python 3. I have based my code on Python 2 example code, written by LiveOverflow. His original code is found in his video. My proxy library is intended to work like this: there is a proxy object containing a server-side object and a client-side object. The client-side object mimics a server, while the server-side object mimics a client. The two pass data to each other through the parent proxy object. To initiate the proxy, the script using the library instantiates the proxy with the port the client side is going to host on and the ip address and port the server side is going to connect to. Here is the code:

            I have solved the issue. Browsers use a random port to send http/https requests. As I understand, this can be circumvented by adding a colon and the desired port number to the end of the url.

            Netty Proxy to duplicate traffic
            Asked 2017-Mar-08 at 21:00

            I am exploring a way to duplicate traffic from a netty proxy to two servers. i.e. instead of the general implementation:

            Server1 -> Proxy -> Server 2

            I would like to do the following:

            Server 1 -> Proxy -> Server 2 and Server 3

            Server3->Proxy is dropped

            Hence each message is sent to both server 2 and server 3.

            I just have one constraint that the communication between proxy and server 2 should not be blocked because of server 3 (in case server 3 is slow etc.).

            I am starting from the following code: https://github.com/dawnbreaks/TcpProxy

            Unfortunately, I am not too familiar with netty, but the implementation seems highly optimal for my purpose. I would like to understand:

            1. How to create a new channel for Server 3
            2. Which API to override for communication to Server 3
            3. How to read and drop messages from Server 3
            ...

            Answered 2017-Mar-08 at 21:00

            saw your chat in IRC #netty.

            A couple of things here. Your Proxy would need to have a server side that Server 1 connects to. Then the Server 2 and Server 3 need to either except a connection from the Proxy or you could use UDP (depending) to receive data from the Proxy.

            Netty has an example of a proxy server. This would work in your case and its really easy for the third part. Simply put you would use the existing example and open a new connection which would be to Server 3. Now what you can do is take both channels from the Proxy (Client Connections to server 2 and 3) Put them in a channel group and write one time to two servers!. My example code that is edit will... allow communications from server 1 to server 2 through the proxy mutually and allow for mutual talk while server 3 only can receive data but if server 3 replies to the proxy, the proxy doesn't do anything. You may want to add a handler to release buffers or handle data written back that shouldn't be from server 3. Also from here this should get you started but check out netty documents, api, examples and ppts they are super helpful!

            I will attach some modified code to show you and here is a link to the examples.

            Netty Proxy Server Examples

            So for the Example you would edit the HexDumpProxyFrontendHandler.class and just add a second Bootstrap for the new client for Server 3.

            TcpProxy running in Docker not working

            When I run a NodeJS TcpProxy (the one below) in my localhost, it works (I mean, it console.logs "Hi" when visiting localhost through a browser). But, when I launch a container with that same program inside it, it doesn't work.

            Your script listens on 127.0.0.1, which is your local loopback device. In this case its the loopback device of your container, not 'your' localhost. I am assuming that expose and -p are publishing the port of the ip address of your container to your host. Not its loopback device.

            So you need to listen on your external ip address. Try listening to 0.0.0.0
