Application Notes
General Application Notes
Internet Connection
A typical Internet access application of the ZyXEL Device is shown below. For a small office, there are some
components needs to be checked before accessing the Internet.
Before you begin
Setting up the Windows
Setting up the ZyXEL Device
Troubleshooting
Before you begin
The ZyXEL Device is shipped with the following factory default:
1. IP address = 192.168.1.1, subnet mask = 255.255.255.0 (24 bits)
2. DHCP server enabled with IP pool starting from 192.168.1.33
3. Default SMT menu password = 1234
Setting up the PC (Windows OS)
1. Ethernet connection
All PCs must have an Ethernet adapter card installed.

If you only have one PC, connect the PC's Ethernet adapter to the ZyXEL Device's LAN port with
a crossover (red one) Ethernet cable.
If you have more than one PC, both the PC's Ethernet adapters and the ZyXEL Device's LAN port
must be connected to an external hub with straight Ethernet cable.
2. TCP/IP Installation
You must first install TCP/IP software on each PC before you can use it for Internet access. If you have already
installed TCP/IP, go to the next section to configure it; otherwise, follow these steps to install:
In the Control Panel/Network window, click Add button.
In the Select Network Component Type windows, select Protocol and click Add.
In the Select Network Protocol windows, select Microsoft from the manufacturers, then select
TCP/IP from the Network Protocols and click OK.
3. TCP/IP Configuration
Follow these steps to configure Windows TCP/IP:
In the Control Panel/Network window, click the TCP/IP entry to select it and click Properties
button.
In the TCP/IP Properties window, select obtain an IPaddress automatically.
Note: Do not assign arbitrary IP address and subnet mask to your PCs, otherwise, you will not be able to access
the Internet.
Click the WINS configuration tab and select Disable WINS Resolution.
Click the Gateway tab. Highlight any installed gateways and click the Remove button until there
are none listed.
Click the DNS Configuration tab and select Disable DNS.
Click OK to save and close the TCP/IP properties window
Click OK to close the Network window. You will be prompted to insert your Windows CD or disk.
When the drivers are updated, you will be asked if you want to restart the PC. Make sure your
ZyXEL Device is powered on before answering Yes to the prompt. Repeat the above steps for
each Windows PC on your network.
Setting up the ZyXEL Device

The following procedure is for the most typical usage of the ZyXEL Device where you have a single-user
account (SUA). The ZyXEL Device supports embedded web server that allows you to use Web browser to
configure it. Before configuring the router using Browser please be sure there is no Telnet or Console login.
1. Retrieve ZyXEL Device Web
Please enter the LAN IP address of the ZyXEL Device in the URL location to retrieve the web screen from the
ZyXEL Device. The default LAN IP of the ZyXEL Device is 192.168.1.1. See the example below. Note that
you can either use http://192.168.1.1 or https://192.168.1.1
2. Login first
The default password is the default SMT password, '1234'.

Click “Apply” to complete the Connection Wizard.
Setup the the ZyXEL Device as a DHCP Relay
What is DHCP Relay?
DHCP stands for Dynamic Host Configuration Protocol. In addition to the DHCP server feature, the P2302
supports the DHCP relay function. When it is configured as DHCP server, it assigns the IP addresses to the
LAN clients. When it is configured as DHCP relay, it is responsible for forwarding the requests and responses
negotiating between the DHCP clients and the server. See figure 1.

Setup the ZyXEL Device as a DHCP Client
1. Toggle the DHCP to Relay in menu 3.2 and enter the IP address of the DHCP server in the 'Relay Server
Address' field.
Menu 3.2 - TCP/IP and DHCP Ethernet Setup

Configure an Internal Server Behind SUA
Introduction
If you wish, you can make internal servers (e.g., Web, ftp or mail server) accessible for outside users, even
though SUA makes your LAN appear as a single machine to the outside world. A service is identified by the
port number. Also, since you need to specify the IP address of a server in the ZyXEL Device, a server must
have a fixed IP address and not be a DHCP client whose IP address potentially changes each time it is powered
on.
In addition to the servers for specific services, SUA supports a default server. A service request that does not
have a server explicitly designated for it is forwarded to the default server. If the default server is not defined,
the service request is simply discarded.
Configuration
To make a server visible to the outside world, specify the port number of the service and the inside address of
the server in 'Menu 15.2.1', Multiple Server Configuration. The outside users can access the local server using
the ZyXEL Device's WAN IP address which can be obtained from menu 24.1.

Configure a PPTP server Behind SUA
Introduction

PPTP is a tunneling protocol defined by the PPTP forum that allows PPP packets to be encapsulated within
Internet Protocol (IP) packets and forwarded over any IP network, including the Internet itself.
In order to run the Windows 9x PPTP client, you must be able to establish an IP connection with a tunnel server
such as the Windows NT Server 4.0 Remote Access Server.
Windows Dial-Up Networking uses the Internet standard Point-to-Point (PPP) to provide a secure, optimized
multiple-protocol network connection over dial-up telephone lines. All data sent over this connection can be
encrypted and compressed, and multiple network level protocols (TCP/IP, NetBEUI and IPX) can be run
correctly. Windows NT Domain Login level security is preserved even across the Internet.
Window98 PPTP Client / Internet / NT RAS Server Protocol Stack
PPTP appears as new modem type(Virtual Private Networking Adapter) that can be selected when setting up a
connection in the Dial-Up Networking folder. The VPN Adapter type does not appear elsewhere in the system.
Since PPTP encapsulates its data stream in the PPP protocol, the VPN requires a second dial-up adapter. This
second dial-up adapter for VPN is added during the installation phase of the Upgrade in addition to the first
dial-up adapter that provides PPP support for the analog or ISDN modem.
The PPTP is supported in Windows NT and Windows 98 already. For Windows 95, it needs to be upgraded by
the Dial-Up Networking 1.2 upgrade.

This application note explains how to establish a PPTP connection with a remote private network in the ZyXEL
Device SUA case. In ZyNOS, all PPTP packets can be forwarded to the internal PPTP Server (WinNT server)
behind SUA. The port number of the PPTP has to be entered in the SMT Menu 15 for ZyXEL Device to
forward to the appropriate private IP address of Windows NT server.
Example
The following example shows how to dial to an ISP via the ZyXEL Device and then establish a tunnel to a
private network. There will be three items that you need to set up for PPTP application, these are PPTP server
(WinNT), PPTP client (Win9x) and the ZyXEL Device.
oPPTP server setup (WinNT)
Add the VPN service from Control Panel>Network
Add an user account for PPTP logged on user
Enable RAS port
Select the network protocols from RAS such as IPX, TCP/IP NetBEUI
Set the Internet gateway to ZyXEL Device
oPPTP client setup (Win9x)
Add one VPN connection from Dial-Up Networking by entering the correct
username & password and the IP address of the ZyXEL Device's Internet IP
address for logging to NT RAS server.
Set the Internet gateway to the router that is connecting to ISP
oZyXEL router setup
