DDS-Router and ROS2 nodes at the same device about dds-router

[rsanchez15]

Hi @mockbot

Could you give me more information about the error you are getting? It would also be good to know what is your network infrastructure, specifically if you are using any containerization technology such as Docker and what is the network configuration you are using (virtual network for the dockers, shared host network, etc.).

Could you attach also the .yml configuration file that you are using to set up the DDS Router?

There is something else that is not entirely clear. On the one hand you say you are running everything on the same machine but you present a scenario with two LANs. I guess your use case is to connect both networks using the DDS Router right? Please correct me if I am wrong.

Sorry for trying good old FOXY LTS, first tries with GALACTIC did not throw reported errors THX4ALL

For anyone looking back, I've experienced this too. If I try to run the Husky simulator on the same VM dds_router is already running it refuses to start with port conflict issues under Foxy.
