Description

## Issue template

- Hardware description: Dell Inspiron 15 (Ubuntu 20.04 wsl2)
- RTOS: ESP32 Node MCU
- Installation type: micro_ros_setup
- Version or commit hash: foxy

#### Steps to reproduce the issue
- Set the micro-ros credentials through the command "idf.py menuconfig";
- Compile and flash the INT32_SUB_PUB example on esp32;

In the Ubuntu 20.04 wsl2 Host machine:
* Windows 11 side:
- Open the windows power shell as admin user and type: "netsh interface portproxy add v4tov4 listenport=8888 listenaddress=0.0.0.0 connectport=8888 connectaddress="
- Go to the firewall and create a new inbound rule for port 8888 ;
* Ubuntu 20.04 wsl2 side:
- install the micro-ROS package and dependencies following this tutorial: https://micro.ros.org/docs/tutorials/core/first_application_linux/
- run the micro_ros_agent: "ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888"
#### Expected behavior
I was expecting the same behavior when use a native linux machine: the esp32 finding the ros agent and publishing messages over ros2.
#### Actual behavior
Esp32 tries to connect to the ros agent but it is not finding it and eventually i get this message on the esp32 monitor: "Failed status on line 57: 1. Aborting".

Research direction

Start by reproducing the reported setup with the micro_ros_agent udp4 --port 8888 entry point, checking the WSL2 portproxy and firewall configuration described in the issue. Done means the ESP32 discovers the agent and publishes messages over ROS 2 as it does on native Linux.
