5 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.
If you are using the ZyWALL in router mode, continue with the next section. For bridge mode, skip to Section
7.
6 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.

ENGLISH
10
This figure helps explain the main fields in the wizard screens.
1Click VPN in the HOME screen (you may need to scroll up to see the link) to open the VPN wizard.
Note: Your settings are not saved when you click Back.
2Use 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.
3Use 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.

ENGLISH
11
Note: 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.
Note: 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.
Perfect Forward Secrecy (PFS): None allows faster IPSec setup, but DH1 and DH2 are more secure.
4Use this screen to configure IKE (Internet Key
Exchange) tunnel settings.
5Use this screen to configure IPSec settings.

ENGLISH

6.1 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.
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).
6Check your VPN settings. Click Finish to save the
settings.
7Click 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.

7 Troubleshooting
7.1 Set Up Your Computer’s IP Address
This section shows you how to set up your computer to receive an IP address in Windows 2000, Windows NT
and Windows XP. This is ensures that your computer can communicate with your ZyWALL.
1In Windows XP, click Start, Control Panel.
In Windows 2000/NT, click Start, Settings, Control Panel.
2In Windows XP, click Network Connections.
In Windows 2000/NT, click Network and Dial-up Connections.
Problem Corrective Action
None of the LEDs
turn on.
Make sure that you have the power adaptor connected to the ZyWALL and plugged in to an
appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you should
contact your local vendor.
Cannot access
the ZyWALL from
the LAN.
Check the cable connection between the ZyWALL and your computer or hub. Refer to
Section 1 for details.
Ping the ZyWALL from a LAN computer. Make sure your computer’s Ethernet card is
installed and functioning properly.
In the computer, click Start, (All) Programs, Accessories and then Command Prompt. In
the Command Prompt window, type "ping" followed by the ZyWALL’s LAN IP address
(192.168.1.1 is the default) and then press [ENTER]. The ZyWALL should reply. Otherwise,
refer to Section 7.1.
If you’ve forgotten the ZyWALL’s password, use the RESET button. Press the button in for
about 10 seconds (or until the PWR LED starts to blink), then release it. It returns the
ZyWALL to the factory defaults (password is 1234, LAN IP address 192.168.1.1 etc.; see
your User’s Guide for details).
If you’ve forgotten the ZyWALL’s LAN or WAN IP address, you can check the IP address in
the SMT via the console port. Connect your computer to the CONSOLE port using a console
cable. Your computer should have a terminal emulation communications program (such as
HyperTerminal) set to VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow
control and 9600 bps port speed.
Cannot access
the Internet.
Check the ZyWALL’s connection to the Ethernet jack with Internet access. Make sure the
Internet gateway device (such as a DSL modem) is working properly.
Click WAN in the navigation panel to verify your settings.
Cannot establish
a VPN connection
Make sure the ZyWALL and the remote IPSec router use the same VPN settings. Click VPN
in the navigation panel to configure advanced settings.
Access a web site to check that you have a successful Internet connection.
