Tried to find the answer in the archive with no luck...

Is this setup possible?  Is there anyway to secure the traffic between
the LAN, OPT1, OPT2 interfaces?
Wireless device(s) and PC(s) need to access services on the server(s)


Wireless device(s) (172.16.0.2->.254)

			     DLINK WAP====OPT1 (172.16.0.1)
