Router IP

IP Address and Subnet Mask. This shows both the Router’s IP Address and Subnet Mask, as seen by your
network. The default IP Address is 192.168.16.1, and the default Subnet Mask is 255.255.255.0. In most cases,
keeping the default values will work.

DHCP Server Setting

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. If you choose to enable the Router’s DHCP server option, you must make sure
there is no other DHCP server on your network.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then select Disabled (no other DHCP features will be available).

Static DHCP. Every time a PC reboots, it is assigned a new local IP address by the Router. If you want a PC to be
assigned the same IP address every time it reboots, then click the Static IP button.

On the DHCP Client List screen, enter the static local IP address in the Assign this IP field, and enter the MAC
address of the PC in the To this MAC field. Then click the Enabled checkbox. When you have finished your entries,
click the Save Settings button to save your changes. Click the Cancel Changes button to cancel your changes.
To exit this screen, click the Close button.

Figure 5-9: Static DHCP Client List

If you want to see a list of DHCP clients, click the DHCP Client Table button. On the DHCP Client Table screen, you
will see a list of DHCP clients with the following information: Client Name, Interface, IP Addresse, and MAC
Addresse. To save the information, select Static DHCP Client List. From the To S ort by drop-down menu, you can
sort the table by Client Name, Interface, IP Address, or MAC Address. To view the most up-to-date information,
click the Refresh button. To exit this screen, click the Close button.

Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router’s default IP address is 192.168.16.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller
than 192.168.1.254. The default Starting IP Address is 192.168.16.100.

Maximum Number of Users. Enter the maximum number of PCs that you want the DHCP server to assign IP
addresses to. This number cannot be greater than 253. The default is 50.

IP Address Range. The range of DHCP addresses is displayed here.
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”

The default is 0 minutes, which means one day.

Static DNS (1-3). Your ISP will provide you with at least one DNS (Domain Name System) Server IP Address.
WINS. The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use

a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.

The Setup Tab - DDNS

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other
server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers, DynDNS.org or
TZO.com. If you do not want to use this feature, keep the default setting, Disabled.

The Setup Tab - MAC Address Clone

A MAC address is a 12-digit code assigned to a unique piece of hardware for identification. Some ISPs will
require you to register a MAC address in order to access the Internet. If you do not wish to re-register the MAC
address with your ISP, you may assign the MAC address you have currently registered with your ISP to the Router
with the MAC Address Clone feature.

The Setup Tab - Advanced Routing

This tab is used to set up the Router’s advanced functions. Operating Mode allows you to select the type(s) of
advanced functions you use. Dynamic Routing will automatically adjust how packets travel on your network. Static
Routing sets up a fixed route to another network destination.

different IP address for the Internet. To enable NAT, click Enabled. To disable NAT, click Disabled.

Dynamic Routing (RIP)

network’s layout and exchange routing tables with the other router(s). The Router determines the network packets’
route based on the fewest number of hops between the source and the destination. This feature is

building a route to an entire network, be sure that the network portion of the IP address is set to 0. For
example, the Router’s standard IP address is 192.168.16.1. Based on this address, the address of the routed
network is 192.168.16, with the last digit determining the Router’s place on the network. Therefore you would
