I spoke with a T-Mobile support person on 19-FEB-2024 who said the MTU setting needs to be 1300. This is what I did and it works for me (W10); your mileage may vary.

  1. Disconnect from GlobalProtect VPN
  2. Open Windows Control Panel
  3. Open Network and Sharing Center
  4. Click Change Adapter Settings
  5. Right-click the ethernet connection with the subheading PANGP Virtual Ethernet Adapter Secure
  6. Select Properties
  7. Click Yes
  8. Click Configure
  9. Click the Advanced tab
  10. Click MTU
  11. Change the value to 1300
  12. Click OK
  13. Close all windows
  14. Connect to GlobalProtect VPN and wait several minutes to ensure you don’t lose internet connectivity
