I have tried to use ettercat which showed not to be the software I really needeed. There is one point where I don't know what happened but it crashed and did not want to start anymore. I think it has messed with the network. After this, the sub-net packets were not forwarded anymore to the internet.
I could not give much more details since I did not record what happened.
