You should not need to open any ports on your router.
Do you have Monocle Gateway installed on a computer inside your network? That is what is needed first. The Monocle Gateway service running on this computer must listen on port 443 and the Alexa devices must be able to access this computer (on port 443) inside your local network.
The Monocle Gateway service does communicate over the Internet to coordinate when an Alexa device requests a camera stream, but you don’t need to expose any inbound ports for this to work. All the streaming data is maintained locally inside your private network.
