Protocol between Google TV and Google TV 4

[rpatw]

Hi 

In order to setup firewall between two network  I would  like to know the protocol used between Virtual Remote Control app Google TV on my Android (on one network) and the Google TV 4K (second network) . 

Using a tcpdump on my linux system I see nothing.

Any information about it would help me.

Thank

Chromecast with Google TV is a consumer device designed to be used in a home (i.e. there is no expectation it would be used in such an environment), so Google simply doesn't maintain a list of that kind of information unfortunately. The only thing I can suggest is to setup the firewall as you normally would and look at the block logs when you try to use the remote control.
