- Setup VPN, but NAT in front of Customer Gateway. Something like this:
A. Using MAC address from Customer device
B. Using NAT device public IP
C. Using Customer gateway IP
----I think it should be B
"The public IP address value must be static. If your customer gateway is behind a network address translation (NAT) device that’s enabled for NAT traversal (NAT-T), use the public IP address of your NAT device, and adjust your firewall rules to unblock UDP port 4500. "
