Unable to receive data frames in docker container

[birneamstiel]

First of all, thanks for this great contribution.

I'm trying to run this driver within a docker container in the WSL on the same windows machine which is running motive (as the natnet server).

I'm having trouble receiving data – not sure whether it is due to issues with this driver or more general networking issues. The driver can connect properly and receive initial data frames but fails to receive data frames afterwards.

This is the output of the launch command:

The docker container is running in net=host mode and also the WSL is configured to use the mirrored networking mode.

Did anyone manage to get this driver to run successfully within a docker container? Maybe even under WSL?
