ET9200 Port Problem

Hi!

I´m trying to ping my ET9200 on port 12000 with static IP adresses in my LAN, there should be a reply from my CCCam 2.3.0

If I use the same config file on my Dreambox 800 on Gemini Project it works flawless, but my ET9200 on Openpli 3.8.7 does not reply.

I´m using the command

SERVER LISTEN PORT : 12000

on both machines.

Do I have to consider something else?

Thanks,

Jo
