Details

I'm running ROS humble using cyclonedds on 2 computers.

The computers connected via ethernet. The ethernet interface of Computer 1 is called eth0 and the one of Computer 2 is called enp89s0. I can ping them and I can even receive udp packets when running echo "Test message" | nc -u -w1 192.168.0.51 7648 so I know the ports are not blocked. One more detail, the ROS nodes are running in docker containers but they share the host's network so that shouldn't be a source of problem as far as I know.

I'd really appreciate the help, I'm trying to switch from FastDDS as it's causing issues and I wouldn't like to give up on Cyclone as well. Thanks
