Actually, that's a config option on dd-wrt to put it into a bridge mode
with the WAN and LAN ports all bridged together.  I do that all the
time.  I even have a wrt610N running with split SSID with one SSID
having NAT and the other SSID with tighter security and no NAT at a
remove site.  Love dd-wrt.
