GitHub user marcoodamo added a comment to the discussion: VPN Redundancy

Hi rajujith, thanks

To clarify my previous question, what we are specifically looking for is VPN 
failover functionality within a VPC. The goal is to have two IPsec tunnels 
configured between the CloudStack VPC and a remote peer—one active and one 
standby. If the primary tunnel goes down due to any failure (such as 
connectivity loss or router issues), the secondary tunnel should automatically 
become active, ensuring uninterrupted VPN connectivity without requiring manual 
intervention. This setup is essential for maintaining high availability and 
redundancy for our VPN connections.

Does Apache CloudStack (version 4.18, using KVM hypervisor) natively support 
this kind of IPsec VPN tunnel failover within a VPC? If not, is there a 
recommended approach or workaround to achieve this behavior, possibly through 
external monitoring or scripting?
