HOWTO: How are DNS requests apportioned if you have multiple servers listed for DNS resolution?

This article applies to:

  • Firewall Suite 4.X

Question:

How are DNS requests apportioned if you have multiple servers listed for DNS resolution?

Procedure:

Firewall Suite uses the round robin approach for DNS. Each request will be sent to a single DNS server (if there are three DNS servers defined, one out of three requests will hit server 1). If at some point the DNS server becomes saturated and is not responding, the DNS event sent will time out and will not resend to the other two servers.
