Which of the following will ensure that this functions correctly?
The customer gateway IP address for the second VPN connection must be publicly accessible.
The virtual gateway IP address for the second VPN connection must be publicly accessible.
The customer gateway IP address for the second VPN connection must use dynamic routes.
The customer gateway IP address for the second VPN connection must be privately accessible and be the same public IP address that you are using for the first VPN connection.
Explanations:
The customer gateway IP address for the second VPN connection must be publicly accessible to establish a successful VPN tunnel. Both VPN connections need to communicate through public IP addresses to route the traffic correctly.
The virtual gateway IP address does not need to be publicly accessible. The virtual gateway is part of the cloud infrastructure and does not require public access; it primarily serves as a point for the VPN connections to terminate.
The customer gateway IP address for the second VPN connection does not need to use dynamic routes. It can use static routing as long as the routes are properly configured and the VPN connections are established correctly.
The customer gateway IP address for the second VPN connection must be publicly accessible. Having the same public IP address as the first VPN connection for a second connection would not allow for redundancy, as both tunnels would attempt to route through the same public IP. Each connection should ideally have its own unique public IP.
