Overview
The ZyWALL 5 is a 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. When the ZyWALL is in router mode,
you can also insert a 3G wireless card to add a second WAN. 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.

Do the following to make hardware connections for initial setup.
1 Use 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.
2 Use another Ethernet cable to connect the WAN port to an Ethernet jack with Internet access.
3 Insert 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. You can optionally insert a 3G wireless card to access the Internet
wirelessly via a 3G network. See the ZyWALL Turbo Card guide for more information about the extension
card. See the user’s guide about installing a wireless LAN card. At the time of writing, you can use the
following 3G wireless cards in the ZyWALL.

4 Internet Access Setup and Product Registration
1 Click 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.
" 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.
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).
Ethernet Encapsulation
Configure a Roadrunner service in the
NETWORK WAN screens (use the WAN
tab).
ENGLISH
7
To not have the connection up all the time, specify an idle time-out period (in seconds) in Idle Timeout.

ENGLISH
9
" 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.
You can assign TCP/IP configuration via DHCP to computers connected to the DMZ ports. Otherwise,
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.
" You do not need to configure DMZ with bridge mode, skip to Section 7.
1 Click NETWORK > DMZ in the navigation panel.
2 Specify 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.
3 Click Apply.
4 By 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.
ENGLISH
10
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).
The following example allows access from the WAN1 to an HTTP (web) server on the DMZ. The server has a
private IP address of 10.0.0.20.
1 Click ADVANCED > NAT in the
navigation panel and then Port
Forwarding.
2 Select the WAN connection (WAN1) for
which you want to configure port
forwarding rules.
3 Select the Active check box.
4 Type a name for the rule.
5 Type the port number that the service
uses.
6 Type the HTTP server’s IP address.
7 Click Apply.
7 Firewall
You can use the ZyWALL without configuring the firewall.
The ZyWALL’s firewall is pre-configured to protect your LAN from attacks from the Internet. By default, no
traffic can enter your LAN unless a request was generated on the LAN first. The ZyWALL allows access to the
DMZ from the WAN or LAN, but blocks traffic from the DMZ to the LAN.
If you are using the ZyWALL in router mode, continue with the next section. For bridge mode, skip to Section
10.
ENGLISH
11
8 VPN Rule Setup
A VPN (Virtual Private Network)
tunnel gives you a secure
connection to another computer or
network.
A gateway policy identifies the
IPSec routers at either end of a VPN
tunnel.
A network policy specifies which
devices (behind the IPSec routers)
can use the VPN tunnel.
This figure helps explain the main fields in the wizard screens.
1 Click the Wizard icon ( ) in the HOME screen and then the VPN Setup link to open the VPN wizard.
" Your settings are not saved when you click Back.
2 Use this screen to configure the gateway policy.
Name: Enter a name to identify the gateway policy.
Remote Gateway Address: Enter the IP address or
domain name of the remote IPSec router.
ENGLISH
12
3 Use this screen to configure the network policy.
Leave the Active check box selected.
Name: Enter a name to identify the network policy.
Select Single and enter an IP address for a single IP
address.
Select Range IP and enter starting and ending IP
addresses for a specific range of IP addresses.
Select Subnet and enter an IP address and subnet
mask to specify IP addresses on a network by their
subnet mask.
" Make sure that the remote IPSec router uses the same security settings that you configure in
the next two screens.
Negotiation Mode: Select Main Mode for identity protection. Select Aggressive Mode to allow more incoming
connections from dynamic IP addresses to use separate passwords.
" Multiple SAs (security associations) connecting through a secure gateway must have the
same negotiation mode.
Encryption Algorithm: Select 3DES or AES for stronger (and slower) encryption.
Authentication Algorithm: Select MD5 for minimal security or SHA-1 for higher security.
Key Group: Select DH2 for higher security.
SA Life Time: Set how often the ZyWALL renegotiates the IKE SA (minimum 180 seconds). A short SA life
time increases security, but renegotiation temporarily disconnects the VPN tunnel.
Pre-Shared Key: Use 8 to 31 case-sensitive ASCII characters or 16 to 62 hexadecimal ("0-9", "A-F")
characters. Precede a hexadecimal key with a "0x” (zero x), which is not counted as part of the 16 to 62
character range for the key.
Encapsulation Mode: Tunnel is compatible with NAT, Transport is not.
IPSec Protocol: ESP is compatible with NAT, AH is not.
ENGLISH
13
Perfect Forward Secrecy (PFS): None allows faster IPSec setup, but DH1 and DH2 are more secure.
8.1 Using the VPN Connection
Use VPN tunnels to securely send and retrieve files, and allow remote access to corporate networks, web
servers and e-mail. Services work as if you were at the office instead of connected through the Internet.
4 Use this screen to configure IKE (Internet Key
Exchange) tunnel settings.
5 Use this screen to configure IPSec settings.
6 Check your VPN settings. Click Finish to save the
settings.
7 Click Close in the final screen to complete the
VPN wizard setup. Continue with the next section
to activate the VPN rule and establish a VPN
connection.
ENGLISH
14
For example, the “test” VPN rule allows
secure access to an web server on a
remote corporate LAN. Enter the server’s
IP address (10.0.0.23 in this example) as
your browser’s URL. The ZyWALL
automatically builds the VPN tunnel when
you attempt to use it.
Click SECURITY > VPN in the navigation
panel and then the SA Monitor tab to
display a list of connected VPN tunnels
(the “test” VPN tunnel is up here).
9 Anti-Spam Setup
Use anti-spam to have the ZyWALL check for unsolicited commercial or junk e-mail (spam).
" You must have already subscribed to the anti-spam service to use the feature (see page 6).
1 Click the Wizard icon in the HOME screen and then Anti-Spam Setup to open the anti-spam wizard.
2 Select the locations where you
have e-mail servers. An icon of an
e-mail server appears at each spot
you select. In this example the e-
mail servers are on the LAN.
" WAN 2 represents the 3G
wireless Internet
connection available when
you insert a 3G wireless
card (optional).
ENGLISH
15
You can also use the anti-spam whitelist and blacklist to identify legitimate e-mail and spam. See the anti-
spam chapter in the User’s Guide for details.
3 The ZyWALL recommends which
traffic flows to scan for spam based
on the locations of your e-mail
servers.
4 Use this screen to enable anti-
spam and select which traffic flows
the ZyWALL scans for spam. The
recommended traffic flows are
already selected. You generally
only need to select traffic directions
that have incoming e-mail from
outside e-mail servers.
5 Click Apply.
6 Click Close in the final screen to
complete the anti-spam wizard
setup.
7 Congratulations, you have
configured the ZyWALL to scan for
spam e-mail.
