LABEL DESCRIPTION
IP Address setting
Obtain an IP Address
Automatically (DHCP) When you enable this, the NBG6818 gets its IP address from the network’s DHCP server
(for example, your ISP). Users connected to the NBG6818 can now access the network
(i.e., the Internet if the IP address is given by the ISP).
The Web Configurator may no longer be accessible unless you know the IP address
assigned by the DHCP server to the NBG6818. You need to reset the NBG6818 to be
able to access the Web Configurator again (see
Section 13.6 on page 136 for details
on how to reset the NBG6818).
Also when you select this, you cannot enter an IP address for your NBG6818 in the field
below.
Static IP Address Click this if you want to specify the IP address of your NBG6818. Or if your ISP or network
administrator gave you a static IP address to access the network or the Internet.
IP Address Type the IP address in dotted decimal notation. The default setting is 192.168.1.2. If you
change the IP address you will have to log in again with the new IP address.
Subnet Mask The subnet mask specifies the network number portion of an IP address. Your NBG6818
will automatically calculate the subnet mask based on the IP address that you assign.
Unless you are implementing subnetting, use the subnet mask computed by the
NBG6818.
Gateway Enter a gateway IP address (if your ISP or network administrator gave you one) in this
field.
DNS Server
First DNS Server
Second DNS Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information (and
the NBG6818'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. If you chose User-Defined , but leave the IP address set
to 0.0.0.0, User-Defined changes 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 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 to the NBG6818.
Cancel Click Cancel to reload the previous configuration for this screen.
