You can have a DNS listener which is a floating IP address in the LTM sense, to provide HA failover of the listener. Or you can have standalone DNS listeners which are different IP addresses ( and the client will failover between them ), or you can have DNS Anycast where the DNS listener is the same and is redistributed into routing via different VLANs. Then use routing to push clients to the correct listener.
Seems like you may be having issues with the HA functionality - maybe look at MAC masquerading.
