Not able to start Proxy and VPN tunnel when there is no network

Not able to startTunnel from App proxy provider or NETunnelProvider , when there is no network on the machine.

Whenever I am starting tunnels , I get change of status to disconnected.
in the system log I get as below

[com.apple.networkextension:] NESMVPNSession[Primary Tunnel:XXXXX:YYYYY:(null)] in state NESMVPNSessionStateIdle: received start message
[com.apple.networkextension:] NESMVPNSession[Primary Tunnel:XXXXX:YYYYY:(null)]: Leaving state NESMVPNSessionStateIdle
[com.apple.networkextension:] NESMVPNSession[Primary Tunnel:XXXXX:YYYYY:(null)]: Entering state NESMVPNSessionStatePreparingNetwork
[com.apple.networkextension:] NESMVPNSession[Primary Tunnel:XXXXX:YYYYY:(null)]: No network available
[com.apple.networkextension:] NESMTransparentProxySession[Primary Tunnel:XXXXX:YYYYY:(null)]: Leaving state NESMVPNSessionStatePreparingNetwork
[com.apple.networkextension:] NESMTransparentProxySession[Primary Tunnel:XXXXX:YYYYY:(null)]: Entering state NESMVPNSessionStateStopping, timeout 20 seconds

Please let me know is there a way to start tunnels when there is no network ?

This is a result of the status checks that the NEVPNConnection API makes before starting a VPN. Like you mentioned, you will probably see this in any provider that uses NEVPNConnection to state the tunnel, so that means NEAppProxyProvider, NETransparentProxyProvider, and NEPacketTunnelProvider. I have seen other Enhancement Requests related to this functionality (r. 73447260), so I would recommend that you do the same and open an Enhancement Request to alter the way this API works to allow a connection to a local server that may not have connectivity to the wider internet.

Just ran into this as well. Paradoxically, my Network Extension would provide internet connectivity, but because there is none, it cannot get started.
