I want to work from another country and show that I am working from USA

As far as I am aware, every Netgear Orbi router has the same OpenVPN option in the 'Advanced Setup'.  The process is a bit tricky. (I have memories of a lot of membling and swearing.)

OpenVPN is a two-step process.

Most customers have IP addresses that can change over time, so Step 1 is to set up a Dynamic DNS name on the DDNS menu. I did not realize at the time that a "free" No-IP account had to be used at least once a month or it would disappear.  Rather than fight it, I paid the $24.95/year.

Step 2 is to set up OpenVPN, using the DDNS entry as one of the parameters.  I took all the defaults.

Orbi produces configuration files for Windows computers, 'non-Windows' (Linux), and smartphones.  I downloaded all three parameter files to my PC and printed out the instructions for each.

The 'fun part' is testing whether it works or not.

Loaded OpenVPN for Android on my phone.  Emailed the configuration file to my self and downloaded it to the phone.  Put the phone on LTE data. Opened OpenVPN. Imported the configuration. and "presto".

Loaded OpenVPN on a Windows laptop.  This time, set the phone up as a Hot Spot, connected the laptop to the phone, opened OpenVPN, imported configuration, etc.  (much swearing... but it works now)

Linux laptop has OpenVPN built in. Did the same thing.

The Big Difference I see is that I can load whatever software I want on my devices.  OpenVPN would have worked from a coffee shop, library, etc. etc.  I never tried the combination of Hot Spot/OpenVPN on the phone and then connect the laptop.
