HTTP/3 inspection

Gateway supports inspection of HTTP/3 traffic, which uses the QUIC protocol over UDP. To enable HTTP/3 inspection, go to Settings > Network and enable Proxy for UDP.

​​ Browser limitations

The following browsers do not support HTTP/3 inspection:

• Google Chrome
• Safari
• Firefox

Gateway will automatically force all traffic from these browsers to fall back to HTTP/2, thus allowing you to enforce your HTTP policies.
