Configuring iQuery for GTM / DNS

Hey Arron_F​ 

In your case, add BIG-IP LTMs into the DNS using their internal Self-IPs, assuming they are reachable through the MPLS/dark fibre

 internally. IQuery would happen through this private link. However, when you define virtual servers within the server objects, the following procedure is recommended. 

You can add either a virtual server or a pool-level monitor to achieve more precise control.

Creating BIG-IP LTM virtual server objects for BIG-IP servers that reside behind a firewall, NAT

The IP address that you define as the virtual server address for a BIG-IP LTM virtual server is the internet-facing firewall NAT address that clients use to access the virtual server services. The translation address of a virtual server is the private network address defined for the virtual server on the BIG-IP LTM system.

For example, consider a case in which the BIG-IP LTM system's virtual server private network address is 10.0.0.111, and the firewall Internet-facing NAT address is 65.61.115.223.

When you add the BIG-IP LTM system's virtual server to the BIG-IP DNS system, you enter the IP addresses in the General Properties section, as follows:

Address 65.61.115.223

Translation 10.0.0.111
