2 Accessing the Web Configurator

Use this section to configure the WAN interface for Internet access.

1 Launch 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

7.1 to set your computer’s IP address.

3 Change the login password by entering a new

password and clicking Apply.

2 Click Login (the default password 1234 is already

entered).

4 Click Apply to replace the ZyWALL’s default

digital certificate.

ENGLISH

5 The 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.

6 Check the Network

Status table. If the WAN status is not Down and there is an

IP address, go to

Section 5.

If the WAN status is Down (or there is not an IP address), click Internet Access and use Section 4 to configure WAN.

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.

ENGLISH

1 Click MAINTENANCE in the

navigation panel and then

Device Mode.

2 Select Bridge and configure a

(static) IP address, subnet mask and gateway IP address. These apply to the ZyWALL’s LAN and WAN interfaces.

3 Click Apply. The ZyWALL

restarts.

4 Internet Access Setup and Product Registration

1 Click Internet Access in the HOME screen 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.

ENGLISH

• Ethernet Encapsulation

Configure a Roadrunner service in the NETWORK WAN screens (use the WAN tab).

• 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.

2 Click 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 trial application. Otherwise, click Skip and then Close to complete Internet access setup.

3 If 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.

4 Wait for the registration progress to finish.

ENGLISH

5 The following screen displays if the registration

was not successful. Click Return to go back to the Device Registration screen and check your settings.

ENGLISH

6 Click 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 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

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

This figure helps explain the main fields in the wizard screens.

1 Click 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.

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.

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.

ENGLISH

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.

4 Use this screen to configure IKE (Internet Key

Exchange) tunnel settings.

5 Use this screen to configure IPSec settings.

ENGLISH

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.

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).

7 Troubleshooting

Problem Corrective Action

None of the LEDs turn on.

Cannot access the ZyWALL from the LAN.

Cannot access the Internet.

Cannot establish a VPN connection

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.

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.

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. 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.
