VPN issues
All devices and home network are good. Signal strength is 2 bars (weak, but functional). Spouse needs to set up VPN to work from home, but even IT from the office could not get VPN to work via T-Mob...

Yay! I am glad you figured it out. utun (tun short tunneling) is interface created by Mac following any VPN installation. I guess limiting that too, should work, if you don't see gpd0 specifically.
I was wondering since you have the latest version of GP app >= 5.2.4, you should be able to update the MTU through the app settings. Check here GP documentation:
