GCP IPsec VPN HA

Dear all,

I would like to know how to establish a redundant IPsec VPN connection to a redundant VM-500 (not cluster) deployed in GCP.

Should we use GCP Load balancer with external IP and load balance to a single PAN?

If so the GCP network LB does not perform DNAT to the Palo Alto so the PAN will receive the public IP as destination in IP packet.

If VPN session is setup outbound then GCP will NAT to different public IP, how to solve that?

Should we connect directly to the NIC0 public IP instead? We need to use NAT-T?

Someone here has best practices on this topic?
