Communication between Master and Slave

[painstephane]

Hi,

I have a domoticz installation D1 on my local network with a switch light device and I would have an other domoticz installation D2 on an other network.

I would like D2 will be the master installation and D1 will be the slave installation like explain in the wiki page 'Setting up Device sharing'. So after that, I can see my switch light device on D2.

So the questions are :
1) Which ports must be open for the communication between D1 and D2 ? Only the port 6144 on the D2 network ?
2) If, for exemple, I would switch light on, can I do that with D2 ? If yes, which ports must be open on the D1 network ?

Thank you for your answer

Best regards

Stéphane
