Summary:
When developing and testing your Alexa skills in a corporate environment, you might need to know the TCP/UDP ports that Echo uses so that they could be opened on a corporate firewall, allowing developers to connect Echo to the network for testing. Please note that Echo is a consumer device and at the moment does not support enterprise networks directly. Therefore, you will need to create a personal/consumer Wi-Fi network to be able to use Echo within your company’s network.
Here is the list of ports you need to open:
* Output TCP: *, 80, 8080, 443, 40317, 67, 68
* Output UDP: *, 53, 123, 40317, 49317, 33434, 1900, 5000, 5353
* Input TCP: 8080, 443, 40317
* Input UDP: 53, 67, 68, 1900, 50000, 5353, 33434, 49317, 40317
