A02. Will the ZyWALL work with my Internet connection?
The ZyWALL is designed to be compatible with most network environment (cable or xDSL modems). Most
external Cable and xDSL modems use an Ethernet port to connect to your computer so the ZyWALL can be
place between the computer and the External modem. As long as your Internet Access device has an Ethernet
port, you can use the ZyWALL. Besides, if your ISP supports PPPoE you can also use the ZyWALL, because
PPPoE had been supported in the ZyWALL.
A03. What do I need to use the ZyWALL?
You need an xDSL modem or cable modem with an Ethernet port to use the ZyWALL. The ZyWALL has two
Ethernet ports: LAN port and WAN port. You should connect the computer to the LAN port and connect the
external modem to the WAN port. If the ISP uses PPPoE Authentication you need the user account to enter in
the ZyWALL.
A04. What is PPPoE?
PPPoE stands for Point-to-Point Protocol over Ethernet that is an IETF draft standard specifying how a
computer interacts with a broadband modem (i.e. xDSL, cable, wireless, etc.) to achieve access to the
high-speed data networks via a familiar PPP dialer such as 'Dial-Up Networking' user interface. PPPoE supports
a broad range of existing applications and service including authentication, accounting, secure access and
configuration management.
A05. Does the ZyWALL support PPPoE?
Yes. The ZyWALL supports PPPoE since ZyNOS 2.50.
A06. How do I know I am using PPPoE?
PPPoE requires a user account to login to the provider's server. If you need to configure a user name and
password on your computer to connect to the ISP you are probably using PPPoE. If you are simply connected to
the Internet when you turn on your computer, you probably are not. You can also check your ISP or the
information sheet given by the ISP. Please choose PPPoE as the encapsulation type in the ZyWALL if you are
using PPPoE service provided by your ISP.
A07. Why does my Internet Service Provider use PPPoE?
PPPoE emulates a familiar Dial-Up connection. It allows your ISP to provide services using their existing
network configuration over the broadband connections. Besides, PPPoE supports a broad range of existing
applications and service including authentication, accounting, secure access and configuration management.
