Chapter 13 DHCP Server Table 47 Network > DHCP Server > Advanced (continued) LABEL First DNS Server Second DNS Server Third DNS Server DESCRIPTION Select Obtained From ISP if your ISP dynamically assigns DNS server information (and the NBG6616's WAN IP address). The field to the right displays the (read-only) DNS server IP address that the ISP assigns. Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP address in the field to the right. Select DNS Relay to have the NBG6616 act as a DNS proxy. The NBG6616's LAN IP address displays in the field to the right (read-only). The NBG6616 tells the DHCP clients on the LAN that the NBG6616 itself is the DNS server. When a computer on the LAN sends a DNS query to the NBG6616, the NBG6616 forwards the query to the NBG6616's system DNS server (configured in the WAN 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. Select None if you do not want to configure DNS servers. If you do not configure a DNS server, you must know the IP address of a computer in order to access it. Apply Click Apply to save your changes back to the NBG6616. Cancel Click Cancel to begin configuring this screen afresh. 13.4 DHCP Client List Screen The DHCP table shows current DHCP client information (including IP Address, Host Name and MAC Address) of network clients using the NBG6616's DHCP servers. Configure this screen to always assign an IP address to a MAC address (and host name). Click Network > DHCP Server > Client List. Note: You can also view a read-only client list by clicking Monitor > DHCP Server. Figure 74 Network > DHCP Server > Client List The following table describes the labels in this screen.
