We have the need to connect to a non-Meraki site to site VPN gateway. Our Meraki is behind a NAT, and as such when attempting a VPN connection, the Meraki replies back with its private IP address, causing the VPN connection to fail. Our remote VPN source requires a router behind a NAT to reply with its public IP, which is not a feature that Meraki supports. Is this a feature that can be added?
