When this option is set to On, the Express L128/L128T acts as a DHCP server 
and will dynamically assign  IP, network mask, default gateway, and DNS ad-
dresses to any device which transmits a broadcast DHCP request.  The ad-
dresses assigned are based on the Express L128/L128T’s own IP address and 
will be within the same network.   This mode is most commonly used with the 
NAT functionality. The default is Off.
