Hello, I've got multiple roboter platforms in a WiFi Network which communicate with each other, but also have some internal communication. If they do drive out of the range of the WiFi I obviously want the internal communication to still be held up. But as the network is gone and they loose their IP-Adress (and as far as I understand each node is just at an IP adress on a specific port) the internal communictaion is gone as well. I'm using the latest ROS2 galactic with the Cyclone DDS implementation.

Is there any way to fix this problem, maybe another DDS version?

Thanks.
