It's certainly doable. The most important thing you have to do is make sure your BIG-IP has access to the Internet and can successfully route out to the Google IP (ie. set a default outbound route).

 

 

At some point however, you may come to find that configuring specific IP addresses for remote services like Google is maybe not the best idea, as you have no control over those IPs which can change without warning.

Of course now you must also ensure that the BIG-IP can resolve the remote host names as well.
