Implementing in the same type situation - haven't finished testing but for the VS I used a made up IP for the destination, made sure Vlans and tunnels was set to Enabled on - in the selected box empty. Then created a Host entry under System DNS for the FQDN to that IP. Since it's static local the F5 should never try to resolve off box, then use the FQDN nodes for the pool. Used the resolved Cnames for the pools members.

 

Just an option. Follows what Brad noted.
