Network

9.1 Overview

This chapter discusses the network configuration screens. The Network screens allow you to configure TCP/IP and PPPoE settings for the NSA.

9.2What You Can Do

•Use the TCP/IP screen (Section 9.4 on page 176) to assign the NSA a dynamic or static IP address and DNS information.

•Use UPnP port mapping (Section 9.5 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 9.6 on page 182) to configure PPPoE settings for a direct Internet connection.

9.3What 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.

PPPoE

Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct Internet connection if you do not have a router. PPPoE is a dial-up connection. You need a username and password from your Internet Service Provider (ISP) to set up the connection.
