DHCP Server Enabled You can enable or disable the DHCP server. By
enabling the DHCP server the router will
automatically give your LAN clients an IP
address. If the DHCP is not enabled then you’ll
have to manually set your LAN client’s IP
addresses; make sure the LAN Client is in the
same subnet as this broadband router if you
want the router to be your LAN client’s default
gateway
Lease Time The DHCP when enabled will temporarily give
your LAN clients an IP address. In the Lease
Time setting you can specify the time period that
the DHCP lends an IP address to your LAN
clients. The DHCP will change your LAN client’s
IP address when this time threshold period is
reached
IP Address Pool You can select a particular IP address range for
your DHCP server to issue IP addresses to your
LAN Clients.
Note: By default the IP range is from: Start IP
192.168.0.100 to End IP 192.168.0.200. If you
want your PC to have a static/fixed IP address
then you’ll have to choose an IP address outside
this IP address Pool

Click <Apply> at the bottom of the screen to save the above configurations. You can now

3.4 NAT
Network Address Translation (NAT) allows multiple users at your local site to access the Internet
through a single Public IP Address or multiple Public IP Addresses. NAT provides Firewall
protection from hacker attacks and has the flexibility to allow you to map Private IP Addresses to
Public IP Addresses for key services such as Websites and FTP. To meet various field
applications, XRT-D NAT function can be disabled to as a regular router. If NAT is disabled, all
LAN side workstations must have valid IP addresses for Internet access. If the router is used for
routing application, not for Internet access, then the NAT function can be disabled.
