I wish I new this filter SOONER!!
I use this filter all the time to isolate traffic that runs over different TCP ports. You can do the same thing with UDP ports. The membership operator is a fantastic filter to learn with Wireshark!

    Do you have any experience with management engine packets? Is there are rule that can be used to block them using an IDS/IPS? Can enforcing macsec make it difficult for someone to unplug the ethernet cable and plug in a cable which gives them lan access to the NIC?

    Finally some one who gets it! I used to spend so much time at one place big on finger-pointing trying to get someone to run a trace. They always wanted to claim it wasn't their issue but no one wanted to prove it wasn't their issue because it might prove it actually was their issue. People who point fingers don't care about about finding solutions they care about avoiding blame.

    I’m troubleshooting a TCP connection between a server and a group of PLCs. I’m closing in on the root of the problem and it seems that the PLCs fail to respond to the server when it coincides with a pair of TCP acked unseen segment + TCP spurious retransmission packets. Your videos are helping me a lot on building the knowledge I need to understand this. So thank you very much for doing them 👍🏻👍🏻👍🏻

    Supergood!!! Congratulation Chris and thanks for amazing course. I was struggling jut a lil bit to get through Task 6 (Special Operators) - with match / contains filters seems like regex doesn't work properly (at least on macOS). - "quotes" has to be used, otherwise syntax is red - incorrect (I know you have them in text, they're just missing from video). - "\." is evaluated also as syntax incorrect on macOS - seems like backslash should be omitted and filter works just fine (I know that it's in contrary with regex use, may be a Wireshark bug on macOS, or just a little inconsistency?) Many thanx again and have great day everyone.
