Dynamic Host Configuration Protocol (DHCP) is a communication protocol that lets network administrators to manage
centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the
Internet Protocol, each machine that can connect to the Internet needs a unique IP address. When an organization sets
up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer. If computers move to another location in
another part of the network, a new IP address must be entered. DHCP lets a network administrator to supervise and
distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into
a different place in the network.
The DHCP conditional server configuration page is effective only if DHCP mode in LAN settings page is set to Server or
Relay Agent.
Click on check box “OFF”, “Server” and “Relay”. Then click on “Apply” to finalize the setting.

NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one
network to a different IP address known within another network. One network is designated the inside network and
the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP
addresses and reverse the global IP addresses of incoming packets back into local IP addresses. This ensure security
since each outgoing or incoming request must go through a translation process, that also offers the opportunity to
