[ros-users] [Discourse.ros.org] [Next Generation ROS] No communication if no gateway is set

[Lennart Nachtigall]

Hi,
I ran into trouble with a simple network setup consisting of two computes connected via a switch. I noticed ros2 will only send data in case a gateway is set (the gateway address doesn't need to be reasonable - for example I just set it to the ip of the switch).

This leads me to the question. Why do I need to set a gateway?
