Devices are not Joined when I replace my gateway

Hello Every One,
I have a Gateway referenced DRAGINO
Because of remote work I replace the Gateway from our company into home
The gateway is seen by the application server at once I connect it to the Internet
But the devices are not seen by the Gateway
My question is:
Is there any relation between the coordinates of Gateway and my trouble ?

Thank you for the quick response ^^

possible issue - IP firewall settings to pass thru
