@eskimo, I'm going to need to back track my back track. After doing some more testing and examining of the route table I am still having an issue when I change the PTP IPv4 Settings to go from a Split Tunnel configuration to a Full Tunnel configuration, i.e. PTP includedRoutes = defaultRoute. From initial connection Full Tunnel config works exactly as expected, but once I change to Split and then back to Full the system appears to think there is no network. Thoughts of where I can look? Thx

Disregard this post. I found that not all the routes needed were getting set. Sorry for the issue.

Quinn, Thanks that helps a lot.

Weird. I could have sworn I attached it. Try #2. I also don't see anything that indicates a "Last Exception Background" crash.txt

Quinn, Thank you for the response. Just to be clear, there is no other supported way to configure a utun device in newer macOS releases, correct? I want to make sure I haven't missed something. Scott
