Foreign Relay
Dear all,
I have ROS Groovy running on a remote system, but need to have topics available locally as well.
I've looked into multimaster_fkie and foreign_relay. I got foreign_relay working locally (running a ros master on two different ports), however when I did the same setup on two different laptops (connected to the same router / on the same subnet, no firewall) I only could see the topics but not the messages. I have the same issue with multimaster_fkie (which I would not like to use because of the mandatory discovery process, I much prefer foreign_relay's approach to have the remote master specified explicitely).
I saw the other questions on this site, but though the symptoms are precisely the same as answers.ros.org/question/10074/help-troubleshooting-foreign-relay, the fix did not help. I see answers.ros.org/question/12420/foreign_relay-problem has the exact same issue, but no answer. I hope that somebody using foreign_relay successfully could shed some light on this issue.
