Overview
The ZyWALL 35 is a load-balancing, dual WAN firewall with VPN, bandwidth management, content filtering,
anti-spam, anti-virus, IDP (Intrusion Detection and Protection) and many other features. You can use it as a
transparent firewall and not reconfigure your network nor configure the ZyWALL’s routing features. The
ZyWALL increases network security by adding the option to change port roles from LAN to DMZ for use with
publicly accessible servers. This guide covers the initial connections and configuration needed to start using
the ZyWALL in your network.
See the User’s Guide for more information on all features.
You may need your Internet access information.
This guide is divided into the following sections.

Do the following to make hardware connections for initial setup.
1Use an Ethernet cable to connect the LAN/DMZ port to a computer. If you configure these ports as DMZ
ports in the LAN or DMZ screen through the web configurator, you can also use Ethernet cables to connect
public servers (web, e-mail, FTP, etc.) to the LAN/DMZ ports.
2Use another Ethernet cable(s) to connect the WAN 1 port and/or WAN2 port to an Ethernet jack with
Internet access.
3Insert the ZyWALL Turbo extension card to use the anti-virus and IDP features or insert a wireless LAN
card to use the wireless LAN feature. See the ZyWALL Turbo Card guide for more information about the
extension card. See the user’s guide about installing a wireless LAN card.
4Use the included power adaptor to connect the power socket (on the rear panel) to a power outlet.

5Look at the front panel. The PWR LED turns on. The SYS LED blinks while performing system testing and
then stays on if the testing is successful. The ACT, CARD, LAN/DMZ and WAN LEDs turn on and stay on
if the corresponding connections are properly made.
2 Accessing the Web Configurator
Use this section to configure the WAN 1 interface for Internet access.
5The HOME screen opens.
The ZyWALL is in router mode by default. Continue to the next step if you want to use routing features
such as NAT, DHCP and VPN.
Go to Section 3 if you prefer to use the ZyWALL as a transparent firewall.
1Launch your web browser. Enter 192.168.1.1 (the
ZyWALL’s default IP address) as the address.
If the login screen does not display, see Section
10.1 to set your computer’s IP address.
2Click Login (the default password 1234 is already
entered).
3Change the login password by entering a new
password and clicking Apply.
4Click Apply to replace the ZyWALL’s default
digital certificate.

Check the
Network
Status table.
If the WAN 1
status is not
Down and
there is an IP
address, go
to Section 5.
If the WAN 1
status is
Down (or
there is not an
IP address),
click the
Wizard icon
and use
Section 4 to
configure
WAN 1.
Use the NETWORK WAN screens if you need to configure WAN 2. You can also configure load balancing
between the WAN ports.
3 Bridge Mode
When you set the ZyWALL to bridge mode, it functions as a transparent firewall. Do the following to set the
ZyWALL to bridge mode.

4 Internet Access Setup and Product Registration
1Click the Wizard icon ( ) in the HOME screen and then
the Internet Access Setup link to open the Internet access
wizard.
Enter the Internet access information exactly as given to you.
If you were given an IP address to use, select Static in the IP
Address Assignment drop-down list box and enter the
information provided.
Note: The fields vary depending on what you select in the
Encapsulation field. Fill them in with the
information provided by the ISP or network
administrator.
Click Apply when you are done.
1Click MAINTENANCE in
the navigation panel and
then Device Mode.
2Select Bridge and
configure a (static) IP
address subnet mask and
gateway IP address for
the ZyWALL’s LAN, WAN,
DMZ and WLAN
interfaces.
3Click Apply. The ZyWALL
restarts.
Skip to Section 5 if you have
servers that you need to be
accessible from the WAN.

• PPP over Ethernet or PPTP Encapsulation
Select Nailed-Up when you want your connection up all the time (this could be expensive if your ISP bills you
for Internet usage time instead of a flat monthly fee).
To not have the connection up all the time, specify an idle time-out period (in seconds) in Idle Timeout.
•Ethernet Encapsulation
Configure a Roadrunner service in the NETWORK
WAN screens (use the WAN 1 tab).

2Click Next to display the screen where you
can register your ZyWALL with myZyXEL.com
(ZyXEL’s online services center) and activate
the free content filtering, anti-spam, anti-virus
and IDP trial applications. Otherwise, click
Skip and then Close to complete Internet
access setup.
Note: Make sure you have installed the ZyWALL Turbo Card before you activate the IDP and anti-virus
subscription services.
Turn the ZyWALL off before you install or remove the ZyWALL Turbo Card.
3If you already have an account at
myZyXEL.com, select Existing
myZyXEL.com account and enter account
information. Otherwise, select New
myZyXEL.com account and fill in the
fields below to create a new account and
register your ZyWALL. Click Next.
4Wait for the registration progress to finish.

5The following screen displays if the registration
was not successful. Click Return to go back to
the Device Registration screen and check your
settings.
6Click Close to leave the wizard screen when
the registration and activation are done.
Note: If you want to activate a standard
service with your iCard’s PIN number
(license key), use the
REGISTRATION Service screen.
See the user’s guide for details.
5 DMZ
The DeMilitarized Zone (DMZ) allows public servers (web, e-mail, FTP, etc.) to be visible to the outside world
and still have firewall protection from DoS (Denial of Service) attacks.
Unlike the LAN, the ZyWALL does not assign TCP/IP configuration via DHCP to computers connected to the
DMZ ports. Configure the computers with static IP addresses (in the same subnet as the DMZ port's IP
address) and DNS server addresses. Use the ZyWALL's DMZ IP address as the default gateway.
Do the following to configure the DMZ if the ZyWALL is in routing mode.
Note: You do not need to configure DMZ with bridge mode, skip to Section 7.

1Click NETWORK, DMZ in the navigation panel.
6 NAT
NAT (Network Address Translation - NAT, RFC 1631) means the translation of an IP address in one network
to a different IP address in another. You can use the NAT Address Mapping screens to have the ZyWALL
translate multiple public IP addresses to multiple private IP addresses on your LAN (or DMZ).
2Specify an IP address and subnet mask for the DMZ
interface.
If you use private IP addresses on the DMZ, use
NAT to make the servers publicly accessible (see
Section 6).
A public IP address must be on a separate subnet
from the WAN port’s public IP address. If you do not
configure NAT for the public IP addresses on the
DMZ, the ZyWALL routes traffic to the public IP
addresses on the DMZ without performing NAT.
This may be useful for hosting servers for NAT
unfriendly applications.
3Click Apply.
4By default, LAN/DMZ ports 1 to 4 are all LAN ports.
To configure a port as a DMZ port, click the Port
Roles tab, select its radio button next to DMZ and
click Apply.
