Transfer data from Unity to another computer with ROS2

[L1MSpace]

I have a goal, to create a connection between two computers. The first computer on Windows 11 has Unity and ROS2 Humble installed. The second computer on Linux (Ubuntu 22.04) has only ROS2 Humble installed.

I was able to run the ros2-for-unity scripts “ROS2 Unity Component”, “ROS2 Talker Example”, “ROS2 Listener Example” in Unity without errors. Afterward, when I type “ros2 topic list” in the console on Windows, I see the “/chatter” topix that Unity creates. But, if I enter the same thing on a second computer on Linux, the “/chatter” topix is not there, i.e. ROS2 on Linux does not see this topix.
Both computers are connected to the same WI-FI network.

Question, does ros2-for-unity support data transfer via topics to another computer with ROS2?
If not, are there then alternative libraries that are suitable for my purpose.

P.S. I used ROS# library for the same purpose in ROS1. There I just had to put in the ip of a second computer on Linux (where ros-master was running), and after that Unity could send and receive data from another computer with ROS2.

Environment:
Windows 11;
Linux (Ubuntu 22.04)
ROS2 Humble (on Windows and Linux);
ros2-for-unity 1.3.0, overlay mode.
