It has been a while since I've worked with v9 but the basics haven't changed. Does the wideIP (WIP) have multiple pools assigned? With global availability (GA) set on the WIP then GTM will always select the first pool on the list if it's available. If not then it selects the second and so on.

 

Do the pools have multiple virtual servers in them? If so what is the pool load balancing method? GTM implements a two-tiered LB scheme. The WIP LB method selects a pool then the pool LB method selects a virtual server addr.

 

Also check that the listener is enabled on the internal and external vlans where it should respond to DNS queries.
