Squid does not proxy UDP traffic (including QUIC). UDP traffic should not be forwarded/redirected/intercepted/etc. to Squid primary TCP listening ports (i.e. http_port, https_port, and ftp_port).

If you see signs of UDP traffic getting to Squid primary TCP ports, then something is misconfigured outside of Squid. In either case, the solution probably lies outside of Squid.


HTH,

HTTPS was reserved for 443. QUIC is also using UDP 443 and not following proper protocol rules.

I do understand that QUIC is HTTP3 and uses UDP over 443 only. Again from a cybersecurity perspective how do you set up this protocol in the proxy ?

Here is the photo of the pcap showing the issue..

Does anyone know what to do to fix this?
