Hi all,
I’ve installed the Home Assistant Docker (stable) on my Synology NAS and did everything the guide told me to. In the Synology NAS firewall I opened port 8123, so now I have access to HA.
Then I connected my Homematic CCU (RaspberryMatic on a Raspberry Pi 3) to the installation which I also did with a guide on this site. (configuration.yaml)
The problem is now:
When a turn off my Firewall on the NAS everything works fine, I see my Homematic devices as entities and even my printer, philips hue and router are found.
When I turn the firewall on, I have Access to the HA Installation, and I can see the CCU. But there is no connection to my Homematic devices, printer, router, philips hue.
What can I do now? Which ports I have to open in my Synology Firewall to get a connection to all my devices? Docker uses the hosts network.
I hope anybody can help. Thank you in advance.
