FYI I found very little info about Per-App VPNs. Most documents go over the configuration files. Start with Network Extension Docs https://developer.apple.com/documentation/networkextension NETunnelProviderManager and NEAppProxyProvider provide the most direct info on Per-App VPNs. NETunnelProviderManager https://developer.apple.com/documentation/networkextension/netunnelprovidermanager NEAppProxyProvider https://developer.apple.com/documentation/networkextension/neappproxyprovider

How does that differ from using a Packet Tunnel? Can you point me in right direction to get started? Ken
