If you change the IP address of the NBG420N in the screen below, you will
need to log into the NBG420N again using the new IP address.

LABEL DESCRIPTION
Get from
DHCP Server
Select this option to allow the NBG420N to obtain an IP address from a DHCP server
on the network. You must connect the WAN port to a device with a DHCP server
enabled (such as a router or gateway). Without a DHCP server the NBG420N will
have no IP address. You need to find out the IP address the DHCP server assigns to
the NBG420N and use that address to log in to the NBG420N again.
User Defined
LAN IP
Select this option to set the NBG420N’s IP address. This setting is selected by
default. Check the IP address is on the same domain as other devices on your
network.
IP Address Type the IP address in dotted decimal notation. The default setting is 192.168.1.1. If
you change the IP address you will have to log in again with the new IP address.
IP Subnet
Mask
The subnet mask specifies the network number portion of an IP address. Your
NBG420N 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 NBG420N.
Gateway IP
Address
Type the IP address of the gateway. The gateway is an immediate neighbor of your
NBG420N that will forward the packet to the destination. In AP Mode, the gateway
must be a router on the same segment as your NBG420N.
DNS Servers

Second DNS
Server
Third DNS
Server
Select From ISP if your ISP dynamically assigns DNS server information. 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.
