Avoid Cisco on MarketPlace
This server looks great on the paper.
It does not support ikev1 (only ikev2). Impossible to speak to the Cisco Support as the server is registered to "CONTINENTAL RESOURCES INC."
I bought a yearly subscription for $1.940. It is a scam!
If you're still using IKE version 1 in 2022, there's something very wrong with your environment.
