How to setup ASG and latency based DNS routing for AWS pfsense vpn
-
We're running AWS pfsense VPN appliance in multiple regions and would like to setup ASG (auto scaling group) and latency based DNS to route users to the closest (lowest latency) regions. However the pfsense instances do not seem to expose health check endpoint OTB that is needed by ASG and to implement proper failover. For instance, if all instances in us-west die, we'd like users to be routed to us-east.
Is there a recommended way to add health check to the AWS pfsense instances?
