some Debian flavors have this built into the WiFi GUI, but I'd like to learn a more generic option in the CLI or config files

sorry for the noob question, thanks for reading

This is something that you want to do with the router, not that it's impossible...

What are you trying to accomplish?

Parameter that can be change to not get direct internet:

submask to 0 (no routing)
no default route

Tools:

web Cockpit
web Webmin
Nmtui
NetworkConfiguration

Are you sure you want to do it at the device level?

Just remove the gateway from the lan settings.

Or iptables, but that's more effort and a new tool to learn.

Purchase and install the firewall-software called iptables. It allows for precise configuration; e.g. blocking any connections to the wider web. May the FOSS be with you!

purchase ?

Yes, I'm perfectly happy to sell a subscription to iptables for just $3.99/mo. PM me to arrange payment.
