The NAT firewalls do not like P2P UDP traffic. Majoritoy of the routers lack the smarts to passtrough QUIC correctly, they need to treat it the same as TCP essentially.

NAT is the devil. bring on the IPoc4lypse

Nat is massively useful for all sorts of reasons which has nothing to do with ip limitations.

NAT isn't dead with IPv6. ISPs assigning a /128 to your residential network is a thing.

QUIC isn’t generally P2P though. Browsers don’t support NAT traversal for it.
