    You can assign your listener address to whatever you want from that internal vlan. It doesn't have to be a floating IP address, but it can be. In the DNS profile you attached to your listener, did you enable 'Use BIND Server on BIG-IP'? Since you defined recursion through named, it'll need to be able to use BIND.

     

    If locally issued GTM queries can't recurse out to the Internet, then it could be something is preventing it from getting out, like a firewall.
