Hi @rrr999 ,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to know about failover of Azure VPN gateway from one region to another.
Apologies for the delay, as I was doing a lab to replicate your requirement
For P2S, I don't think the above solution would work. You will be required to manually switch to the other VPN gateway's FQDN
Refer to this thread: Azure VPN with Azure Traffic Manager
However, for a S2S, we would only require the IP of the VPN gateways.
So, you should be able to configure a load balancing solution such as Traffic Manager to get this achieved.
By Global Load Balancer, I believe you are referring to the Cross-region load balancer
- You will only be able to add a Load Balancer behind a Cross-region load balancer
- You will not be able to add a Public endPoint or a PaaS service behind a L4 Load Balancer.
- So, using a Load Balancer might not suit your requirement
With Traffic Manager, make sure you use Priority based routing so that the Primary Region is always prefered
You can consider using Zone Redundant VPN gateways for Zonal Failures
Thanks,
Kapil
