Hello everyone, I hope you are doing well. By the way, Anton, thank you for this wonderful software. In advance, I apologize for my English; my native language is Portuguese. I've noticed from the server logs that random devices are trying to connect to the server, devices that I don't have and haven't pointed to the server. I only use GT06, and I see several devices from other protocols attempting to connect. How can I block these attempts, as there are many, and it's causing server overload? Here are the records:

If your server is exposed to internet, it's expected that you will get some random noise.
One thing you can do is disable ports that you don't use.
But overall I wouldn't worry about it unless you get too many random messages.
Thank you Anton. I will disable the unused ports.
