Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your NBG-416N, but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your NBG-416N will compute the subnet mask automatically based on the IP address that you entered.
Page 46: Wan Ip And Dns Server Address Assignment
The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG-416N uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server.

Page 101: Network Address Translation (Nat)
Network Address Translation 11.1 Overview This chapter discusses how to configure NAT on the NBG-416N. NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.
Page 102: What You Can Do
The following terms and concepts may help as you read through this chapter. Inside/Outside This denotes where a host is located relative to the NBG-416N, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Page 103 If you do not define any servers , NAT offers the additional benefit of firewall protection. With no servers defined, your NBG-416N filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
