LYNC - Use F5 LTM as reverse proxy?

The guide asks for an internal and external IP for the reverse proxy. Can I just create an external virtual server and forward the ports to the individual FE servers in the pool?

 

I have it set up this way now and am getting a cert error from the testocsconnectivity website. Doesn't seem like a useful error though
