Lync 2013 Edge Configuration

I followed the section on page 26 to manually setup the F5 to load balance the 2013 edge servers:

http://www.f5.com/pdf/deployment-gu...app-dg.pdf

For the internal interfaces it shows load balancing tcp/4443 and tcp/8057 but in the Mircosoft documentation ( http://technet.microsoft.com/en-us/...s.14).aspx ) for firewall configuration it only shows opening these ports for the IP's of the Edge NIC's not for the F5 VIP that load balances it. If traffic can't reach the VIP there's nothing to load balance. Do these ports need to be opened for the VIP as well?
