PiWall Multicasting Problem

[Thomas Black]

Hi all.

I am following CRTDream's guide for a PiWall using CRT monitors: https://crt.gg/piwall/ 

I am having some trouble on the multicasting section of the guide. I have very limited experience in multicasting and have hit a bit of a brick wall. I have attached some screenshots from the guide with a side by side of what I am seeing on my computer. Hopefully they make sense.

Thanks for any help. :)

the guide you are following has a typo, it should be 239.0.1.23 rather than 239.0.1.2.3.

Still, it seems there is something wrong with your ethernet connection, thus the USB ethernet you plugged in isn't "green".
