A is the answer.
If the Security & SD-WAN > Monitor > VPN status page for a given network reports either "NAT type: Unfriendly" or "VPN Registry: Disconnected", there is likely a device upstream of the MX for that site that is preventing AutoVPN from working correctly.
That’s a good one, but tricky. I’m going with D.
Yes, really a good one, but after thinking about it all but one answer can be eliminated:
@SandroZ : Its tricky, yes.. I will go with D
It was not my intention to trick anybody but sometimes to not give away the answer the wording might result convoluted 🙃
The correct answer is D
The NAT unfriendly event is triggered by inconsistent information (port/IP address) between multiple VPN Registry
@SandroZ : we know your tricks and we got the right answers 😀
