You better be aware of what just changed on the Internet. TCP is being replaced with QUIC. UDP is being used more and more instead of TCP. This affects your firewalls. It affects a lot of your network troubleshooting. HTTP/3 has been standardized. Everything is encrypted with QUIC – welcome to the new world of network troubleshooting and security.
