Crestron

Remote access to a Crestron network requires access to HTTPS and to a private port, both of which must be port-forwarded through a firewall.

To distinguish Crestron HTTPS traffic from regular web SSL traffic, it’s helpful to port-forward a variation on port 443, such as 4433, and set that appropriately in the Crestron app.

In addition, it’s necessary for the router to port-forward the port number described as “CIP” in the app, which is typically 41794. Because of cyberhacking, it’s good to change this to a different different port number, and port-forward appropriately.
