An IP address pool typically includes a range private addresses 
that you define. LAN administrators often define private IP 
addresses for use only on their networks. You can also use 
DHCP server pools to distribute multiple public IP addresses, if, 
for example, these are to be shared among a larger set of LAN 
computers. 
 
You can create up to two DHCP server address pools. You can 
define a single pool with addresses that can be assigned to 
your LAN PCs (connected via the Ethernet port) and to a 
USB-connected computer, as long you have assigned to the 
USB and Ethernet interfaces static IP addresses that place 
them in the same subnet. 

 

 

Start/End IP Addresses:

 Specify the lowest and highest 

addresses in the pool, up to a maximum range of 254 
addresses. 

 

Mac Address:

 A MAC address is a manufacturer-assigned 

hardware ID that is unique for each device on a network. 
Use this field only if you want to assign a specific IP 
address to a specific computer (that is, you are creating an 
exception to the dynamic assignment of addresses). The IP 
address you specify will be assigned to the computer that 
corresponds to this MAC address. If you type a MAC 
address here, you must have specified the same IP 
address in both the Start IP Address and End IP Address 
fields. 

 

Net Mask:

 Specifies which portion of each IP addresses in 

this range refers to the network and which portion refers to 
the host (computer). You can use the net mask to 
distinguish which pool of addresses should be distributed to 
a particular subset of computers on your LAN (call a 
subnet). 

 

Domain Name:

 A user-friendly name that refers to the 

subnet that includes the addresses in this pool.  

 

Gateway Address:

 The address of the default gateway for 

computers that receive IP addresses from this pool. If no 
value is specified, then the appropriate LAN (eth-0) or USB 
(usb-0) port address on the device will be distributed to 
each PC as its gateway address, depending on how each 
is connected. See Configuring IP Routes for an explanation 
of gateway addresses.

                                                                26 / 102 

 

DNS/SDNS:

 The IP address of the Domain Name System 

server to be used by computers that receive IP addresses 
from this pool. The DNS translates common Internet names 
that you type into your web browser into their equivalent 
numeric IP addresses. Typically, this server is located with 
your ISP. 

 

SMTP...SWINS (optional):

 The IP addresses of devices 

that perform various services for computers that receive IP 
addresses from this pool (such as the SMTP, or Simple 
Mail Transfer Protocol, server which handles e-mail traffic). 
Contact your ISP for these addresses. 

 

Click on the 

Submit

 button when completed and make sure

5.4 DHCP 

Relay 

Click on the 

DHCP Relay

 link to view the DHCP Relay settings.   

 
Some ISPs perform the DHCP server function for their 
customers' home/small office networks. In this case, you can 
configure the device as a DHCP relay agent. When a computer 
on your network requests Internet access, the ADSL/Ethernet 
router connects your ISP to obtain an IP address and other 
information, and then forwards that information to the computer. 
 

Fill in the DHCP server IP address in the text boxes and select 
an interface name from the dorp down list, then click on the 

Add 

button.
