Link: DNS
Your Service Provider may maintain a Domain Name server. If you have the information for the DNS servers, enter it on the DNS page. If your Gateway is configured to use DHCP to obtain its WAN IP address, the DNS information is automatically obtained from that same DHCP Server.
Link: DHCP Server
Your Gateway can provide network configuration information to computers on your LAN, using the Dynamic Host Configuration Protocol (DHCP).
If you already have a DHCP server on your LAN, you should turn this service off.
If you want the Gateway to provide this service, click the Server Mode
You can also specify the length of time the computers can use the configuration informa- tion; DHCP calls this period the lease time.
