DHCP Server 

This page allows you to change the Dynamic Host Configuration Protocol (DHCP) server settings on the NB16DG. The DHCP 
Server enables computers or devices connecting to the NB16DG to automatically obtain their network configuration settings. By 
default, the DHCP server is enabled.  
 
The LAN IP Address and Subnet Mask fields offer the ability to configure the IP address of the router locally and the subnet mask. 
 

 

 

OPTION 

DEFINITION 

DHCP Server 

Enable or disable the DHCP server.  

LAN IP Address 

 The local IP address of the NB16DG.  

(The computers on your network must use this IP address as their Default Gateway. You can change it if necessary.)

 

Subnet Mask 

 Enter the subnet mask for use on the local network. This would usually be set to 255.255.255.0. 

IP Pool Starting/Ending Address 

Whenever there is a request, the DHCP server will automatically allocate an unused IP address from the IP address pool 
to the requesting computer. You must specify the starting / ending address of the IP address pool 

Lease Time 

Length of the DHCP lease time 

Domain Name 

Optional, this information will be passed to the client 

Primary DNS 

 Optional, this information will be passed to the client 

Secondary DNS 

 Optional, this information will be passed to the client 

Primary WINS 

 Optional, this information will be passed to the client 

Secondary WINS 

 Optional, this information will be passed to the client 

Gateway 

 Optional, this information will be passed to the client 

 
When you have finished configuring the DHCP Server settings, click Save to save your settings. If you want to cancel any changes 
you have made before saving them, click the Undo button. 
 
Use the Clients List button to check the DHCP client list. The Fixed Mapping button allows you to map a specific IP address to a 
specific MAC address. The following pages describe these features in more detail.
