===== Firewall Configuration =====

[[https://en.wikipedia.org/wiki/QUIC|QUIC]] (Quick UDP Internet Connections) runs a stream-multiplexing protocol over Transport Layer Security (TLS) on top of UDP instead of TCP. Be sure you've enabled the port with both TCP //and// UDP.

====== How to verify QUIC is enabled ======

There’s a Chrome extension which will allow you to see the protocols at work on any website.
Install [[https://chrome.google.com/webstore/detail/http2-and-spdy-indicator/mpbpobfflnpcgagjijhmgnchggcjblin|HTTP/2 and SPDY indicator]], and you will see a lightning bolt in the Chrome toolbar. Blue indicates HTTP/2 is enabled. Green indicates HTTP/2 + QUIC. Hover over the lightning bolt to see a more detailed list of protocols in action.
