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.   

z

 

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).   

z

 

Domain Name: A user-friendly name that refers to the subnet that includes the 

addresses in this pool.    

z

 

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.   

z

 

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.   

z

 

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.  

4. 

When you are done defining the pool, click Submit.    

A confirmation page displays briefly to indicate that the pool has been added successfully. 

After a few seconds, the DHCP Server Pool – Add page displays with the newly added pool. 

5. Click 

DHCP Mode in the task bar, then follow the instructions in Setting the DHCP Mode to 

enable the DHCP server.   

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.
