When this option is set to On, the Express XL/XLT 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 XL/XLT’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.
