LAB with Internet

Hi,

 

i'm building a Lab using some solutions of F5 BIG-IP, and i try using it as a router. I configure Inside and external interfaces. Choose my IP of NAT to be my route default in vmware workstation, create a VS with forwarding(IP) with 0.0.0.0/0 *all services. But my hosts can't reach the internet. What was I doing wrong or not is possible to do this? I'm using LTM and AFM to this lab.
