IP Address setting
Obtain an IP Address
Automatically (DHCP) When you enable this, the NBG7815 gets its IP address from the network’s DHCP server
(for example, your ISP). Users connected to the NBG7815 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 NBG7815. You need to reset the NBG7815 to be
able to access the Web Configurator again (see
Section 13.6 on page 139 for details
on how to reset the NBG7815).
Also when you select this, you cannot enter an IP address for your NBG7815 in the field
below.
Static IP Address Click this if you want to specify the IP address of your NBG7815. 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 192.168.123.2. 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 NBG7815
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
NBG7815.
Gateway Enter a gateway IP address (if your ISP or network administrator gave you one) in this
field.
