How to allow the QUIC Protocol and deny all other traffic

Description

This article explains how to block non standard LAN-to-WAN traffic but still allow the QUIC protocol.

Resolution

The QUIC Protocol is not listed under Service Objects on the SonicWall so we need to create them ourselves. It uses UDP Port 80

And UDP Port 443 so we need to create these 2 Service objects – one for each port.

Then add these 2 service objects to a service group

Image

Create an allow access rule for this traffic.

Image

Make sure there is a deny rule in place with lower priority, so that only the QUIC Protocol traffic will be allowed.
