Greetings,
Thank you for clarification.
Regarding VPNs, unfortunately, such data is not available, as tests were carried out with an emphasis on maximum client count and not setup establishment time. This is because this kind of testing would not be accurate in view of the fact that VPN clients might be idle, might be active as well as somewhere in between.
As for NAT, tests were carried out with 3 multiconnections, also without an emphasis on setup establishment times, hence no data regarding your questions were carried out.
I apologise for any inconvenience.
Best regards.
