I am very new to this so would like some more advice. Where do I put this? Also, I have control over it going up but not always over it going down (which appears to be sometimes arbitrary). How do I do that? Btw, in case this matters, my VPN is through Cisco's Anyconnect VPN with Okta's 2-factor authentication. NetworkManager's openconnect VPN does not work any more for me because of the 2-factor authentication (or at least I could not figure it out). Many thanks again and best wishes, Ranjan
