- Make sure that the following router ports are free in order to enable 
smooth network communication with a network-capable device: Router Ports: 
3813, 443, 80, 8080, 3689, 554, *5297, 5298, 5353 UDP multicast
*The last three ports are essential to identify the product over the network 
and are used by the Bonjour protocol. For the device to communicate, 
multicasting must be activated on the router.
