4.2.4 For PPTP Setting 
This setting is most comm only used by DSL providers. 
z  Select “PPTP” button. 
z  Input the User Name, Password and Server  IP Address provided by your ISP.   
z  Chose one WAN connection type DHCP or Static IP. If you chose Static IP, input 
the IP Address. 
z  If you chose “Static” mode, enter the IP address provided by your ISP. Subnet 
Mask: Enter your subnet mask. Gatewa y: Enter your ISPs gateway address. 
z  If you chose “DHCP” mode, enter  the Primary DNS and Secondary DNS 
provided by your ISP 
z   The MTU feature specifies the largest packet size permitted for network 
transmission. Enter the value desired, for mo st Router users, it is recommended 
to use1496. By default, MTU is set at  1496 Primary DNS and Secondary DNS, If 
your ISP provided at least one DNS Server  IP Address, type that IP Address in 
the Primary DNS address fields. You can type up to another DNS Server IP 
Addresses. The Router will utilize these  for quicker access to functioning DNS 
Servers. 
z   Click “Apply” button then finish of setting.

4.3 LAN Setup 
The LAN Setup screen below allows you to specify a private IP address for your 
router’s LAN ports as well as a subnet mask for your LAN segment.

z  System IP address  This is the router’s LAN port IP address (Your LAN clients 
default gateway IP address). 
z   Subnet Mask  Specify a Subnet Mask for your LAN segment. 
z  DHCP Server on  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 . 
z   DHCP IP 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 192.168.10.2 to End  IP 192.168.10.101. 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. 
 
z  DHCP IP Address Reserving  Reserve some IPs to specific computer. You 
need to enter the MAC address of the netwo rk card installed in computer to 
assign a particular IP to it. Enter the re lative values and then click ADD. Also you 
can check the “Auto Setup” checkbox butto n to assign a particular IP to your 
computer.

4.5 NAT 
Network Address Translation (NAT) allows multiple users at your local site to access 
the Internet through a single Public IP A ddress. 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.

4.5.1 DMZ Host Setup 
The DMZ screen allows one local user to be  exposed to the Internet for use of a 
special-purpose service such as Internet gaming and videoconferencing. DMZ 
hosting forwards all the ports for one PC at the same time.
