Configuring Failover DNS to failover inbound connections to specific IP


#1

Is it possible to use the failover DNS feature in conjunction with a failover internet connection so that if ISP connection A fails, external employees connecting to VPN at vpn.domain.tld failover to ISP connection B?

If it is possible, should each ISP be in its own origin pool?

How are health checks configured in this scenario?


#2

In Cloudflare load balancing? Yes in that instance you would typically have each origin in it’s own pool and when the primary is unavailable after N checks the LB would advertise the other IP.

Health checks would be to the specific port of the VPN appliance typically and it would just check that the port is active.
