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 166 ) to assign the NSA a dynamic or static IP
address and DNS information.
• Use UPnP port mapping ( Section 8.5 on page 169 ) 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 172 ) to configure PPPoE settings for a direct Internet
connection.
• Use the Telnet screen ( Section 8.7 on page 173 ) to enable or disable Telnet access.
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.
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.
