When this option is set to On, the Express 4100/4110 acts as a DHCP
server and will dynamically assign IP, network mask, default gateway,
and DNS addresses to any device which transmits a broadcast DHCP
request. The addresses assigned are based on the Express 4100/4110’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.
