Hello. I have a device to which I had to portorwarding to make it work properly. Unfortunately, I notice that it seems to communicate excessively with the outside, at times when it should not be connected, except to check the connection with its own server. I wanted to know if it was possible to limit, in some way, the IPs (ranges, or better still with the domain name), the connection to the device (inbound or outbound or both). In any case, if you have suggestions (firmware updated to the latest version available) i am listening.
Thank you.
