I installed Nordvpn on Ubuntu 24.04, but when connected (using nordvpn connect in the command line) I am unable to see my security cameras on my local network. They are on the same subnet as my computer. I do have firewall protection on my router, blocking the cameras from being seen on the internet, but this is the reverse problem. As soon as I connect to Nordvpn my cameras go blank.
I have reviewed the question this is said to be a duplicate of ("NordVPN local network addresses not reachable when connected"), and that information did not produce the correct answer. Whitelisting the local sublet in an inelegant workaround. But I found the correct answer elsewhere, which I have added at the end, for anyone who still needs an answer.
My settings are below, but I really don't understand any of them. Thank you.

UPDATE: I WAS ABLE TO FIND THE ANSWER to the question, which was not at all included in the question this was said to be a duplicate of: You need to enable "LAN discovery". So at the command line type this:
nordvpn set lan-discovery enable
And afterword nordvpn settings will show the following line:
LAN Discovery: enabled
I'm unsure of the protocol so I'll just leave the correct answer here as part of the question.
