Table 43 Network > DHCP Server > Advanced

LABEL	DESCRIPTION
Static DHCP Table
#	This is the index number of the static IP table entry (row).
MAC Address	Type the MAC address (with colons) of a computer on your LAN.
IP Address	Type the LAN IP address of a computer on your LAN.
DNS Server
DNS Servers	The NBG-418N passes a DNS (Domain Name System) server IP address (in the order
Assigned by DHCP	you specify here) to the DHCP clients. If you do not configure the DNS server, the DHCP
Server	service is disabled and you must have another DHCP sever on your LAN, or else the
	computers must have their DNS server addresses manually configured.
First DNS Server	Select From ISP if your ISP dynamically assigns DNS server information (and the NBG-
Second DNS Server	418N’s WAN IP address). The field to the right displays the (read-only) DNS server IP
	address that the ISP assigns.
	Select User-Definedif you have the IP address of a DNS server. Enter the DNS server's
	IP address in the field to the right. If you chose User-Defined, but leave the IP address
	set to 0.0.0.0, User-Definedchanges to None after you click Apply. If you set a
	second choice to User-Defined, and enter the same IP address, the second User-
	Defined changes to None after you click Apply.
	Select DNS Relay to have the NBG-418N act as a DNS proxy. The NBG-418N's LAN IP
	address displays in the field to the right (read-only). The NBG-418N tells the DHCP
	clients on the LAN that the NBG-418N itself is the DNS server. When a computer on the
	LAN sends a DNS query to the NBG-418N, the NBG-418N forwards the query to the
	NBG-418N's system DNS server (configured in the WAN > Internet Connection
	screen) and relays the response back to the computer. You can only select DNS Relay
	for one of the three servers; if you select DNS Relay for a second or third DNS server,
	that choice changes to None after you click Apply.
Apply	Click Apply to save your changes back to the NBG-418N.
Reset	Click Reset to begin configuring this screen afresh.
