Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) provides a dynamic, “upon request,” IP address to computers
and other networked devices. The router can act as a DHCP server for devices on your local network.
The router provides the flexibility to use different ranges of IP addresses to be assigned by the DHCP server
housed in the router. DHCP configuration is done from the DHCP Configuration page.
To configure DHCP:
1. Optionally select DHCP server enabled on the LAN. If selected, the DHCP server dynamically assigns IP
addresses to all LAN-side devices.
2. Select one of the following to configure the Domain Name Service:
• Obtain DNS information automatically:
The DNS server address will be learned when DHCP client requests are placed over the WAN link.
• Configure DNS manually:
Define DNS server address manually from information you get from your service provider. If you select
this option, provide the following information.
– Domain Name
The router’s DNS domain name as assigned by your service provider.
– Primary DNS Server
IP address where DNS requests will be sent.
– Secondary DNS Server
Optional. IP address where DNS requests will be sent if the primary DNS server is unavailable.
– Primary WINS Server
IP address of the Windows Internet Naming Service where WINS requests will be sent. This maps
NetBIOS names to IP addresses similar to DNS.
– Secondary WINS Server
Optional. IP address where WINS requests will be sent if the primary WINS server is unavailable.
3. Click Next. This displays the Trusted Interface Configuration page.
