The CNWR-811P Multi-Function Wireless A/P Router can also be used to connect your local LAN to a remote LAN or WAN, instead of providing shared Internet Access.

CNWR-811P Features

The CNWR-811P incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.

LAN Features

•

Dual LAN ports.

Normally, the “Hub” port is used to connect the CNWR-811P to your LAN. But if desired, the “PC” port can be used to connect the CNWR-811P directly to your PC, using a standard LAN cable.

NAT Firewall Protection

The firewall protection provided by the CNWR-811P is an intrinsic side effect of NAT (Network Address Translation). All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device.

For internal users, the CNWR-811P acts as a “transparent proxy server”, translating the multiple internal IP addresses into a single external IP address.

For external requests, any attempt to connect to local resources are blocked. The CNWR-811P will not “reverse translate” from a global IP address to a local IP address.

This type of “natural” firewall provides an impregnable barrier against malicious attacks.

CNWR-811P User Guide

Configuration Program

The CNWR-811P contains a HTTP server. This enables you to connect to it, and configure it, using your Web Browser.

Most Browsers should work, provided they support HTML tables and forms.

Preparation

Before attempting to configure the CNWR-811P, please ensure that:

• Your PC can establish a physical connection to the CNWR-811P. The PC and the CNWR-

811P must be directly connected (using the “PC” port on the CNWR-811P) or on the same LAN segment.

• The CNWR-811P must be installed and powered ON.

• If the CNWR-811P's default IP Address (192.168.0.1) is already used by another device,

the other device must be turned OFF until the CNWR-811P is allocated a new IP Address during configuration.

Connecting to the CNWR-811P

To establish a connection from your PC to the device:

1. After installing the CNWR-811P in your LAN, start your PC. If your PC is already run-

ning, restart it.

2. Start your WEB browser.

3. In the Address box, enter "HTTP://" and the IP Address of the CNWR-811P, as in the

following example, which uses the CNWR-811P’s default IP Address:

HTTP://192.168.0.1

4. You should then see the LAN screen.

If you can't connect

If the CNWR-811P does not respond, check the following:

• The CNWR-811P is properly installed, LAN connection is OK, and it is powered

ON.

• Ensure that your PC and the CNWR-811P are on the same network segment. (If

you don't have a router, this must be the case.)

• If your PC is using a fixed IP Address, its IP Address must be within the range

192.168.0.2 to 192.168.0.254 to be compatible with the CNWR-811P's default IP Address of 192.168.0.1. Also, the Network Mask must be set to

255.255.255.0. See Chapter 4 – PC Configuration for details on checking your PC’s TCP/IP settings.

Configuration

Password

If you have assigned a password to the CNWR-811P you will be prompted for the password, as shown below.

Figure 5: Password Dialog

• Leave the "User Name" blank.

• Enter the password for this device, if one has been set.

If no password has been set, this dialog will not appear.

Navigation & Data Input

• Use the menu bar on the left of the screen, and the "Back" button on your Browser, for

navigation.

• Changing to another screen without clicking "Save" does NOT save any changes you may

have made. You must “Save” before changing screens or your data will be ignored.

If OFF (default), data is NOT encrypted before being transmitted.

• If selected, data is encrypted, using the default key, before being

transmitted. The receiving station must be set to 64 Bit Encryption, and have the same Key value in the same position in its key table. Otherwise, it will not be able to decrypt the data.

Default Key

•

Select the key you wish to be the default. Transmitted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only.

Key Table

•

• This table is used when Encrypting and Decrypting data. All

stations, including this Access Point, always transmit data encrypted using their default key. The key number (1, 2, 3, 4) is also transmitted. The receiving station will use the key number (1, 2, 3, 4) to determine which key value to use for decryption. If the key value does not match the transmitting station, decryption will fail.

• The easiest way to ensure there are no problems is to have every

Station, including the Access Point, use the same key table (all entries identical). Then, it does not matter which key is used as the default key.

• If selected, data is encrypted using the key before being transmitted.

The receiving station must be set to use 128 Bit Encryption, and have the same Key value. Otherwise, it will not be able to decrypt the data.

Key

•

Enter the key value you wish to use. Other stations must have the same key.

Routing

RoutingRouting

This Chapter explains the Routing features of the CNWR-811P.

Overview

While the CNWR-811P includes a standard (static) routing table, this feature can be completely ignored if you do not have a router in your LAN.

If you DO have a router, it is necessary to configure BOTH the Router and the Routing table in the CNWR-811P correctly, as described in the following sections.

See

Router Configuration

It is essential that all IP packets for devices not on the local LAN be passed to the CNWR811P, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the CNWR-811P as the Default Route or Default Gateway.

Local Router

The local router is the Router installed on the same LAN segment as the CNWR-811P. This router requires that the Default Route is the CNWR-811P itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.

Destination IP Address

Network Mask

Gateway IP Address

Metric

Normally 0.0.0.0, but check your router documentation.

The IP Address of the CNWR-811P.

Other Routers on the Local LAN

Other routers on the local LAN must use the CNWR-811P’s Local Router as the Default Route. The entries will be the same as the CNWR-811P's local router, with the exception of the Gate- way IP Address.

• For a router with a direct connection to the CNWR-811P's local Router, the Gateway IP

Address is the address of the CNWR-811P's local router.

• For routers which must forward packets to another router before reaching the CNWR-

811P's local router, the Gateway IP Address is the address of the intermediate router.

The default port number for HTTP (Web) connections is port 80, but using port 80 here will prevent the use of a Web "Virtual Server" on your LAN. (See Advanced Internet - Virtual Servers)

You must use this IP Address to connect (see below).

This IP Address is allocated by your ISP. But if using a Dynamic IP Address, this value can change each time you connect to your ISP. So it is better if your ISP allocates you a Fixed IP Address.

To connect from a remote PC via the Internet

1. Ensure your Internet connection is established, and start your Web Browser.

2. In the "Address" bar, enter "HTTP://" followed by the WAN IP Address of the CNWR-

Virtual Servers

This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:

• Your Server does not have a valid external IP Address.

• Attempts to connect to devices on your LAN are blocked by the firewall in this device.

The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below.

• Assign a fixed IP Address to the Server PC, ensuring that

its IP Address is NOT within the address range allocated by the DHCP Server.

• Reserve an IP Address for the Server PC in the DHCP

Server, using the Access Control - PC screen.

Select the protocol (TCP or UDP) used by the Server.

Enter the port number used by the Server to connect to clients.

The port number used by clients when connecting to the Server. This is normally the same as the Internal Port Number. If it is different, this device will perform a "mapping" or "translation" function, allowing the server to use one port address, while clients use a different port address.

From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP, as shown by the "WAN IP Address".

Advanced Internet

Connecting to the Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the WAN Port IP Address (the IP Address allocated to this device by your ISP). e.g.

http://203.70.212.52 ftp://203.70.212.52

It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. If using a Fixed IP Address, it is entered on the WAN screen.

DMZ

This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the Internet, allowing unrestricted 2-way communication between the "DMZ" PC and other Internet users or Servers.

This allows connection to special-purpose servers which require proprietary client software, or 2-way user connections such as Video-conferencing, which requires both users to run special software.

To allow unrestricted access, the Firewall in this device is disabled, creating a security risk.

You should use this feature only if the "Special Applications" feature is insufficient to allow an application to function correctly. This feature should be turned ON only when needed, and left OFF the rest of the time.

Configuring the DMZ

Select Advanced Internet from the navigation bar, then DMZ to see a screen like the following:

Use this to Enable or Disable the DMZ feature. The DMZ feature should be disabled when not required.

Enter the IP Address of the PC on your LAN which will become the "DMZ" PC.

If using DHCP, the LAN IP Address of a PC may change. To solve this problem, you can use either of these methods:

• Assign a fixed IP Address to the DMZ PC, ensuring that its IP

Address is NOT within the address range allocated by the DHCP Server.

• Reserve an IP Address for the DMZ PC in the DHCP Server,

using the Access Control - PC screen.

This is the IP Address Internet users must use to connect to the "DMZ" PC.

This IP Address is allocated by your ISP. It is better if you are using a fixed IP Address, so that it never changes. This will make it easier for Internet users to connect to you. If using a Static IP Address, it is entered on the "WAN" screen.

To Internet users, the IP Address of the DMZ computer is the IP Address allocated by your ISP, as shown by the "WAN IP Address" value.

Access Control

Access ControlAccess Control

This Chapter explains how to configure and use the CNWR-811P's "Access Control" feature.

Overview

The Access Control feature allows administrators to restrict Internet Access by individual PCs. The process uses "Packet Filtering" to block or discard data packets. By default, no packets are blocked or discarded.

To use this feature:

• Set the desired restrictions on the "Everyone" group. All PCs are in the "Everyone" group

unless explicitly moved to another group, using the PC screen.

• Set the desired restrictions on the other groups ("Group 1", "Group 2", etc ) as needed.

• For each PC you wish to move from the "Everyone" group, enter their details on the PCs

screen, and assign them to the desired group

You can limit Internet access for ALL PCs without entering ANY PC data. Simply apply the desired restrictions to the "Everyone" group.

It is also possible to define your own packet filters, and use these filters in addition to the predefined filters. Defining your own filters is optional.

Troubleshooting

TroubleshootingTroubleshooting

This Appendix covers the most likely problems and their solutions.

Overview

This chapter covers some common problems that may be encountered while using the CNWR811P and some possible solutions to them. If you follow the suggested steps and the CNWR811P still does not function properly, contact your dealer for further advice.

General Problems

Problem 1:

Solution 1:

Can’t connect to the CNWR-811P to configure it.

Check the following:

• The CNWR-811P is properly installed, LAN connections are OK, and it

is powered ON.

• Ensure that your PC and the CNWR-811P are on the same network

segment. (If you don't have a router, this must be the case.)

• Ensure that your PC is using an IP Address within the range 192.168.0.2

to 192.168.0.254 and thus compatible with the CNWR-811P's default IP Address of 192.168.0.1. Also, the Network Mask should be set to 255.255.255.0 to match the CNWR-811P. In Windows, you can check these settings by using Control Panel- Network to check the Properties for the TCP/IP protocol.

Internet Access

Problem 1:

Solution 1:

When I enter a URL or IP address I get a time out error.

A number of things could be causing this. Try the following troubleshooting steps.

• Check if other PCs work. If they do, ensure that your PCs IP settings are

correct (IP address, Network Mask, Default gateway and DNS).

• If the PCs are configured correctly, but still not working, check the

CNWR-811P. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)

• If the CNWR-811P is configured correctly, check your Internet connec-

tion (DSL/Cable modem etc) to see that it is working correctly.

Problem 2:

Solution 2:

Some applications do not run properly when using the CNWR-811P.

The CNWR-811P processes the data passing through it, so it is not transparent.

Use the Special Applications feature to allow the use of Internet applications which do not function correctly.

CNWR-811P User Guide

If this does solve the problem you can use the DMZ function. This should work with almost every application, but:

• It is a security risk, since the firewall is disabled.

• Only one (1) PC can use this feature.

• When the DMZ feature is being used, the Special Applications and

Virtual Server features should be disabled.

Wireless Access

Problem 1:

Solution 1:

Problem 2:

Solution 2:

My PC can't locate the Wireless Access Point

Check the following.

• Your PC is set to Infrastructure Mode.

• The wireless channel used matches the wireless channel on the Access

Point.

• The SSID on your PC and the Wireless Access Point are the same.

Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".

• Both your PC and the Wireless Access Point must have the same setting

for WEP. The default setting for the CNWR-811P is disabled, so your wireless station should also have WEP disabled.

• If WEP is enabled, the key tables must match.

• If the Wireless Station access permission on the CNWR-811P's Wireless

screen is set to Only allow access if on this list, then each Wireless station must have its address correctly entered.

• To see if radio interference is causing a problem, see if connection is

possible when close to the Wireless Access Point. Remember that the connection range can be as little as 100 feet in poor environments.

Wireless connection speed is very slow.

The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:

• Access Point location.

Try adjusting the location and orientation of the Access Point.

• Wireless Channel

If interference is the problem, changing to another channel may show a marked improvement.

• Radio Interference

Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated.

• RF Shielding

Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Access Point.

Printing

Appendix A - Troubleshooting

Problem 1:

Solution 1:

Problem 2:

Solution 2:

When I tried to install the Printing software for Peer-to-Peer printing, I received an error message and the installation was aborted.

This may be caused by an existing installation of the printer port software. Before attempting another installation:

• Remove the existing installation

• Restart your PC

To remove an existing printer port installation

1. Open Start - Settings - Control Panel - Add/Remove Programs

2. Look for an entry with a name like "Shared Port", "Shared Printer

Port", "Print Server Driver" or "Print Server Port".

3. Select this item, click "Add/Remove", and confirm the deletion.

I am using Windows 95, and the Printing software installed and ran, but when I selected a port on a CNIG907BP and clicked "Add", the printer was not installed.

Try installing the printer using the standard Windows tools, as follows:

1. Start the Add Printer Wizard.

2. Select Network Printer when prompted "How is the printer attached to

your Computer?", and click Next.

3. When prompted for the Network Path or Queue, enter a dummy value

such as \\123, as shown below. (Do NOT select Yes for "Do you print for MS-DOS programs?")

4. The printer wizard will display a message stating that “The Network

Printer is off-line”. This is OK. Continue the Add Printer Wizard until finished.

5. When finished, go to Control - Panel-Printers. The printer icon will

be grayed out indicating the printer is not ready.

6. Right-click the Printer, and select Properties. Then select the Details

tab, as shown below. (On Windows NT/2000, select the Ports tab.)

CNWR-811P User Guide

7. Click the Add Port button. On the resulting screen, select Other, then

Shared Port, as the port to add, as shown below.

8. Click OK to see the Print Port Configuration screen, as shown below.

Appendix A - Troubleshooting

9. Click the Browse Device button, select the desired Internet Broadband

Gateway, and click OK.

10. Click OK to return to the Printers folders, and right-click on the

Printer. Ensure that the Work off-line option is NOT checked.

The Printer should no longer be grayed out, and is ready for use.
