Multiple DNS Views?

Hi, in our environment we have bind (tcp/udp port 53) behind an L4 virtual server on big-ip ltm virtual edition. "Views" define where the DNS traffic should be going - is there an easy and effective way to maintain source information while routing to the backend servers in our pool? Are we able to have multiple DNS views to accommodate for the different client request sources?

 

OR

 

Is there a better way to handle this, such as with irules, snat pools, etc?

 

Thanks!

    The most simple and straightforward way is to have your DNS servers use your BIG-IP device (a VIP address on it) as the default gateway.

     

    Alternatively, depending on the source address requirement for the DNS views, you can use dedicated SNAT addresses for a particular network as a work-around, by an irule.
