Issue details

I am using a Raspberry Pi 4 connected to an Ardupilot Pixhawk 6C, and I use MAVROS to start it.
When I run ros2 topic list on the Raspberry Pi, I can see the topics being published.
However, when I run ros2 topic list on another computer (OS is ubuntu 22.04) on the same WiFi network, I can't see the topics.

MAVROS version and platform

Mavros: 2.8.0
ROS: Humble
Ubuntu: 22.04

Autopilot type and version

[ x ] ArduPilot
[ ] PX4

Version: ArduCopter V4.5.3

But I use the another computer can't see it, ros2 topic list

yuan@msi-ubuntu:~$ ros2 topic list

I check the ROS_DOMAIN_ID before, the two computer's ROS_DOMAIN_ID=1

Hi @yuan-0816, this does not seem to be a mavros-specific problem. It's worth investigating if you can ros2 topic pub any topic on one machine and ros2 topic echo the same on another.

Yes, I can publish the MAVROS topics by running ros2 launch flight_control flight_prepare.launch.py. However, I cannot receive the topics on another computer. Interestingly, when I publish topics unrelated to MAVROS, the other computer can receive them over WiFi.
