I have an occasional need to switch a few computers from one Internet provider to a different one. Both Internet providers feed into the same network, one at 192.168.0.1 and the other at 192.168.0.254.
So to change from one provider to the other I run nmtui to change the gateway and dns server addresses, then deactivate and reactivate the connection and I'm done.
It's just takes a few minutes, but I'm wondering if there's a way to automate this a bit so instead of having to run nmtui and change all of those numbers, then deactivate and reactivate the connection, I could just have each configuration saved as a text file or something, and just tell network manager "use this configuration now until further notice."
I would create two different NetworkManager connection profiles, called eth0-isp1 and eth0-isp2. You can use the GUI, TUI, or CLI for this. The something like `nmcli connection down eth0-isp1 && nmcli connection up eth0-isp2` should work.
