Hey guys. First of all, sorry about the english.

I have a communication problem between two machines that are on different networks. So I have my PC connected to one router and a Raspberry Pi connected to another router.

PC = Raspberry =

In this scenario, Rasp will be our Master.

So, i can see the topics list on both PC and Raspberry. So, when I publish from Rasp, my PC can hear it, however, when I publish from the PC, my Raspberry cannot hear it.

The ROS_MASTER_URI and ROS_IP are configured correctly. How do I solve this problem?

Did you check if your PC Firewall is blocking the msgs?

sudo ufw disable

Yes, there is no firewall blocking it

probably a routing problem can you ping from the pc to the raspberry ?

The intention is not to be all on the same router. The PC and Raspberry are located on different routers that are connected to each other,
