The case I am concerned about is if the switch connected over DSA in 
this example has a WAN port on it, which can legitimately route to the 
CPU on port 5 but should not route to the LAN ports 0, 1, and 2.  Does 
this VLAN allow direct communication between the WAN and LAN?  Or is 
this prevented by DSA or some other mechanism?

Thanks,
Kevin
