# L4Proxy

L4Proxy is a rudimentary layer 4 proxy, currently supporting IPv4 TCP connections.

## Quick Start

1. Download a version from the [releases page](https://github.com/makkes/l4proxy/releases) for your platform.

1. Create a configuration file. An example is provided [here](./l4proxy_example.yaml)

1. Run the proxy:

   ```

   l4proxy -c l4proxy_example.yaml

   ```

1. Test it:

   ```

   telnet localhost 1313

   ```

   you should now see you're connected to either one of your configured backends.

## How it works

l4proxy is really mostly a proof of concept for my use case of injecting traffic into my on-premise Kubernetes cluster so don't expect miracles from it. However, I appreciate any feedback so please don't hesitate filing issues or PRs.

### Features

* Supports multiple backends

* Exercises health checks for each backend

* Randomly chooses a healthy backend for each new connection
