• Access Control

• Dynamic DNS

• Options

• Schedule

• Port Trigger

• Port Forward

• Port Range Forward

• QoS

Internet

This screen provides access to the DMZ and URL Filter features.

DMZ

This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all users on the Internet.

• This allows almost any application to be used on the "DMZ PC".

• The "DMZ PC" will receive all "Unknown" connections and data.

• If the DMZ feature is enabled, you must enter the IP address of the PC to be used as the

"DMZ PC".

The "DMZ PC" is effectively outside the Firewall, making it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required.

URL Filter

If you want to limit access to certain sites on the Internet, you can use this feature. The URL filter will check each Web site access. If the address, or part of the address, is included in the block site list, access will be denied.

On the Advanced Internet screen, select the desired setting:

• Disable - disable this feature.

• Block Always - allow blocking all of the time, independent of the Schedule page.

• Block By Schedule - block according to the settings on the Schedule page.

Click the Configure URL Filter button to open the URL Filter screen, allowing you to create or modify the filter strings which determine which sites will be blocked.

The URL Filter screen is displayed when the Configure URL Filter button on the Internet screen is clicked.

• To delete all entries, click the Delete All button.

To add to the current list, type the word or domain name you want to block into the field provided, then click the Add button.

Filter strings should be as specific as possible. Otherwise, you may block access to many more sites than intended.

Enable this to allow one computer to have unrestricted access to the Internet. For this PC, the URL filter will be ignored.

If enabled, you must select the PC to be the trusted PC. Select the PC to be the Trusted PC.

Access Control

This feature is accessed by the Access Control link on the Advanced menu.

Overview

The Access Control feature allows administrators to restrict the level of Internet Access available to PCs on your LAN. With the default settings, everyone has unrestricted Internet access.

Restrictions are imposed by blocking "Services", or types of connections. All common Services are pre-defined. If required, you can also define your own Services.

Access Control Screen

To view this screen, select the Access Control link on the Advanced menu.

Data - Access Control Screen

Internet Access

Access Control

Select the desired options for the current group:

• Disable - Nothing is blocked. Use this to create the least

restrictive group.

• Block all Internet access - All traffic via the WAN port is

blocked. Use this to create the most restrictive group.

• Block selected Services - You can select which Services are to

block. Use this to gain fine control over the Internet access for a group.

Blocked Services

This lists all defined Services. Select the Services you wish to block. To select multiple services, hold the CTRL key while selecting. (On the Macintosh, hold the SHIFT key rather than CTRL.)

Schedule

If Internet access is being blocked, you can choose to apply the blocking only during scheduled times. (If access is not blocked, no Scheduling is possible, and this setting has no effect.)

Trusted PCs

"Set Trusted PCs" Button

If enabled, restrictions set on this screen do not apply to Trusted PCs.

Click this button to add or remove PCs of the Trusted PCs. See the following section for details of the Trusted PCs screen.

Trusted PC Screen

This screen is displayed when the Set Trusted PCs button on the Access Control screen is clicked.

Use this screen to add or remove PCs from the current group.

• The "Del >>" button will remove the selected PC (in the Trusted PCs list) from the current

group.

• The "<< Add" button will add the selected PC (in the Other PCs list) to the Trusted PCs

group.

Dynamic DNS (Domain Name Server)

This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.

This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you.

DDNS Services work as follows:

1. You must register for the service at one of the listed DDNS Service providers.

2. After registration, use the Service provider's normal procedure to obtain your desired

Domain name.

3. Enter your DDNS data on the Wireless ADSL Router's DDNS screen, and enable the

DDNS feature.

4. The Wireless ADSL Router will then automatically ensure that your current IP Address is

recorded at the DDNS service provider's Domain Name Server.

5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)

using your Domain name, as shown on this screen.

Dynamic DNS Screen

Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following:

Enter your Username for the DDNS Service. (TZO.com uses your Email address.)

Enter your current password for the DDNS Service. (TZO.com calls this a key.)

• This message is returned by the DDNS Server.

• Normally, this message should be "Update successful"

• If the message indicates some problem, you need to connect to

the DDNS Service provider and correct this problem.

Options

This screen allows advanced users to enter or change a number of settings. For normal operation, there is no need to use this screen or change any settings.

An example Options screen is shown below.

In order to display your local time correctly, you must select your "Time Zone" from the list.

If your region uses Daylight Savings Time, you must manually check "Adjust for Daylight Savings Time" at the beginning of the adjustment period, and uncheck it at the end of the Daylight Savings period.

If you prefer to use a particular NTP server as the primary NTP server, check the checkbox "Use this NTP Server" and enter the Server's IP address in the fields provided.

If this setting is not enabled, the default NTP Servers are used.

Current Time

This displays the current time on the Wireless ADSL Router, at the time the page is loaded.

Port Trigger

If you use Internet applications which use non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the Wireless ADSL Router's firewall. In this case, you can define the application as a "Port Trigger".

The Port Trigger screen can be reached by clicking the Port Trigger on the screen. You can then define your Port Trigger. You will need detailed information about the applica-

tion; this is normally available from the supplier of the application. Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the

client (PC) viewpoint

Port Forward

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.
