<![CDATA[Reaching out to the local network from an HA container?]]>A question of HA and (Docker) networking...

I successfully installed the container, and passed a Zigbee dongle through. Yay!

However, I then realized that when I wanted to talk to a device on my network, the HA container was in a different network from my devices.

Or, if you prefer:

                                                  
                                                  
                                                        
             home     ◄───── cloudron ◄──── HA container
          10.0.0.0/24       10.0.0.xyz      172.X.Y.Z

For some integrations, HA wants to reach out from the container to talk to devices in my home network. Is there anything in the Cloudron model that would let me do this? Or, is the Docker network locked down to explicitly prohibit this for (say) security reasons?

This routing is automatic and should just work as @robi says .

You can open a web terminal of HA and then telnet 10.0.x.y <some-tcp-port> and it should work . Can't use ping in the containers because ping requires net admin privileges and that is disabled in containers.

For a device to see HA, it can leave the Docker network, hit my external DNS provider, and talk to the Docker instance by being passed through by Cloudron. The devices, on the other hand, are issued internal/private IP addresses by my local DHCP server. The HA instance is further removed; while the Cloudron server is on the same network as the devices, the container is not; it, instead, is on an internal, private network on the Cloudron host.

Hence my question.
