What tcp/ip ports have to be open?
What are all the tcp/ip ports that ROS (melodic) needs to be able to use? Other than the one explicitly stated for roscore, I often see other port numbers. Is there an official list somewhere?

This reads like a duplicate of #q198150. Other related Q&As: #q12206. #q12534, #q67171 and #q328698 (and some others).
Summarising: apart from the port on which the Master runs (ie:
11311by default) there is no default/fixed/configurable (range of) port(s).Asked by gvdhoorn on 2020-09-16 09:50:33 UTC
Thanks, please post the answer and I will mark it correct. (The prompt for my question was unexplained incorrect data in some topics going between my nodes. it turned out that there was a firewall blocking some ports - not 11311 and once I opened them all it worked. This is a docker + VPN scenario.)

I've opted to close it as a duplicate instead, as that's what it was.
