Configuring iQuery for GTM / DNS

Hi,

We're starting to look at implementing GSLB for various of our external services.

All of the documentation says we should add our BIG-IP devices in our other data centers via DNS > GSLB > Servers and add using its external IP address.

We do not connect our F5's directly to the internet, instead the NAT is handled by our Firewalls. What IP should I use or how should i configure the server? 

With just their internal management IPs? (Both datacenters are linked via Layer 2 direct fibre so we can contact without having to go out externally)

With the IPs they have in our pool subnet?

Or do i add and put the external address that the GTM DNS listener will be on and have a translation to the internal GTM DNS listener address? 

 

Any pointers are appreciated. 

Thanks
