I just thought of something else. Since I am not worried about security so
much, what if I set up a vlan on the switch and connect the external adapter
to the ADP side of the switch and make the other vlan be my internal NAT.
That way The data can still get to the printers because the adp network is
in tack and I can monitor my internet traffic.

Let me know what you guys think.
