CHAPTER 8
Network
8.1 Overview
This chapter discusses the network configuration screens. The Network screens
allow you to configure TCP/IP and PPPoE settings for the NSA.
8.2 What You Can Do
•Use the TCP/IP screen (Section 8.4 on page 175) to assign the NSA a dynamic
or static IP address and DNS information.
Use UPnP port mapping (Section 8.5 on page 178) to automatically configure
your Internet gateway’s firewall and Network Address Translation (NAT) to allow
access to the NSA from the Internet.
•Use the PPPoE screen (Section 8.6 on page 182) to configure PPPoE settings for
a direct Internet connection.
8.3 What You Need to Know
IP Address
The NSA needs an IP address to communicate with other devices on your network.
The NSA can get an IP address automatically if you have a device on your network
that gives them out. Or you can assign the NSA a static (fixed) IP address.
DNS Server Address
A DNS (Domain Name System) server maps domain names (like www.zyxel.com)
to their corresponding numerical IP addresses. This lets you use domain names to
access web sites without having to know their IP addresses. The NSA can receive
the IP address of a DNS server automatically (along with the NSA’s own IP
address). You can also manually enter a DNS server IP address in the NSA.
