Overview - Setting up the NAT Function

The DSL router is equipped with the network address translation (NAT) function. With address mapping, several users in the local network can access the Internet via one or more public IP addresses. All the local IP addresses are assigned to the public

IP address of the router by default.

One of the characteristics of NAT is that data from the Internet is not allowed into the local network unless it is explicitly requested by one of the PCs in the network. Most Internet applications can run behind the NAT firewall without any problems.

For example, if you request Internet pages or send and receive e-mails, the request for data from the Internet comes from a PC in the local network, and so the router allows the data to pass through. The router opens one specific port for the application.

A port in this context is an internal PC address, via which the data is exchanged between the Internet and a client on a PC in the local network. Communicating via a port is subject to the rules of a particular protocol (TCP or UDP).

If an external application tries to send a call to a PC in the local network, the router blocks it. There is no open port via which the data could enter the local network. Some applications, such as games on the Internet, require several links (that is, several ports), so that players can communicate with each other. In addition, these applications must also be permitted to send requests from other users on the Internet to users in the local network. These applications cannot run if NAT is activated.



Using port forwarding (the forwarding of requests to particular ports), the router is forced to send requests from the Internet for a certain service, for example, a game, to the appropriate port(s) on the PC on which the game is running. Port triggering is a special variant of port forwarding. Unlike port forwarding, the DSL router forwards the data from the port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval for the data transfer is not tied to one specific PC in the network, but rather to the port numbers of the required Internet service.

Where configuration is concerned, you must define a so-called trigger port for the application and also the protocol (TCP or

UDP) that this port uses. You then assign the public ports that are to be opened for the application to this trigger port. The router checks all outgoing data for the port number and protocol. If it identifies a match of port and protocol for a defined trigger port, then it opens the assigned public ports and notes the IP address of the PC that sent the data. If data comes back from the Internet via one of these public ports, the router allows it to pass through and directs it to the appropriate PC. A trigger event always comes from a PC within the local network. If a trigger port is addressed from outside, the router simply ignores it.

Note:

• An application that is configured for port triggering can only be run by one user in the local network at a time.

• After public ports are opened, they can be used by unauthorized persons to gain access to a PC in the local network.

• When the DSL router is supplied, the NAT function is activated. For example, all IP addresses of PCs in the local network are converted to the public IP address of the router when accessing the Internet. You can use NAT settings to configure the DSL router to carry out the following tasks.

• For functions described as follows, IP addresses of the PCs must remain unchanged. If the IP addresses of the PCs are assigned via the DHCP server of the DSL router, you must disable DHCP server as the settings in the local network menu entry for the lease time or assign static IP addresses for the PCs.

• You can enable or disable the NAT function. By default, the NAT function is enabled.



NAT - Virtual Server Setup

By default, DSL router blocks all external users from connecting to or communicating with your network. Therefore, the system is safe from hackers whom may try to intrude into the network and damage it.

However, you may want to expose your network to the Internet in limited and controlled ways in order to enable some applications to work from the LAN (for example, game, voice, and chat applications) and to enable Internet access to servers in the home network. The port forwarding feature supports both functions. This topic is also referred as Local Servers.

The port forwarding page is used to define applications that require special handling by DSL router. All you need to do is to select the application protocol and the local IP address of the computer that is using or providing the service. If required, you may add new protocols in addition to the most common ones provided by DSL router.

For example, if you wanted to use a file transfer protocol (FTP) application on one of your PCs, you would simply select FTP from the list and enter the local IP address or host name of the designated computer. All FTP-related data arriving at DSL router from the Internet henceforth is forwarded to the specific computer.

Similarly, you can grant Internet users access to servers inside your home network, by identifying each service and the PC that provide it. This is useful, for example, if you want to host a Web server inside your home network. When an Internet user points his/her browser to DSL router external IP address, the gateway forwards the incoming HTTP request to your Web server. With one external IP address (DSL router main IP address), different applications can be assigned to your LAN computers, however each type of application is limited to use one computer.

For example, you can define that FTP uses address X to reach computer A and Telnet also uses address X to reach omputer A.

But attempting to define FTP to use address X to reach both computer A and B fails. DSL router, therefore, provides the ability to add additional public IP addresses to port forwarding rules, which you must obtain from your ISP, and enter into the IP addresses pool. Then, you can define FTP to use address X to reach computer A and address Y to reach computer B.



Additionally, port forwarding enables you to redirect traffic to a different port instead of the one to which it was designated.

For example, if you have a Web server running on your PC on port 8080 and you want to grant access to this server to any one who accesses DSL router via HTTP. To accomplish this, do as follows:

Step 1

Define a port forwarding rule for the HTTP service, with the PC IP or host name.

Step 2

Specify 8080 in the Forward to Port field.

All incoming HTTP traffic is forwarded to the PC running the Web server on port 8080. When setting a port forwarding service, ensure that the port is not used by another application, which may stop functioning. A common example is when using SIP signaling in Voice over IP, the port used by the gateway VoIP application (5060) is the same port, on which port forwarding is set for LAN SIP agents.

Note: Some applications, such as FTP, TFTP, PPTP and H323, require the support of special specific application level gateway (ALG) modules in order to work inside the home network. Data packets associated with these applications contain information that allows them to be routed correctly. An ALG is needed to handle these packets and ensure that they reach their intended destinations. DSL router is equipped with a robust list of ALG modules in order to enable maximum functionality in the home network. The ALG is automatically assigned based on the destination port.

Virtual servers are configured for this purpose.



Port Triggering

If you configure port triggering for a certain application, you must determine a so-called trigger port and the protocol (TCP or UDP) that this port uses. You then assign the public ports that are to be opened for the application to this trigger port. You can select known Internet services or manually assign ports or port blocks.



DMZ Host

The demilitarized (DMZ) host feature allows one local computer to be exposed to the Internet. This function is applicable for:

• Users who want to use a special-purpose Internet service, such as an on-line game or video conferencing program, that is not in the port forwarding list and for which no port range information is available.

• Users who are not concerned with security and wish to expose one computer to all services without restriction.

Note: A DMZ host is not protected by the firewall and may be vulnerable to attack. This may also put other computers in the home network at risk. Hence, when designating a DMZ host, you must consider the security implications and and take the appropriate precautions.

You can set up a client in your local network as a DMZ host. Your device then forwards all incoming data traffic from the

Internet to this client. You can, for example, operate your own Web server on one of the clients in your local network and make it accessible to Internet users. As the exposed host, the local client is directly visible to the Internet and therefore particularly vulnerable to attacks (for example, hacker attacks). Enable this function only when necessary (for example, to operate a Web server) and when other functions (for example, port forwarding) are inadequate. In this case, you should take appropriate measures for the clients concerned.

Note: Only one PC per public IP address can be set up as an exposed host.



Security

IP Filtering

Click Security > IP Filtering and the following interface appears. By default, the firewall is enabled. The firewall is used to block document transmissions between the Internet and your PC. It serves as a security gate and permits only authorized traffic to be sent to the LAN.

Note: If the modem is configured to bridge mode only, IP filtering is disabled and the IP filtering interface does not appear.

If the modem does not configure a PVC of Bridge mode, MAC filtering is disabled and the MAC Filtering interface does not appear.



Outgoing

Click Security > IP Filtering > Outgoing and the following page will appear.

By default, all outgoing IP traffic from LAN is allowed, but some IP traffic can be blocked by setting up filters.

Click Add and the page for defining the IP filtering rule appears. In this page, you can create a filter rule to identify outgoing

IP traffic by specifying a new filter name and at least one condition. All specified conditions in the filtering rule must comply with the rule to take effect.

Click Save/Apply to save and activate the filter.



Incoming

Click Security > IP Filtering > Incoming.

By default, all incoming IP traffic from the WAN is blocked when the firewall is enabled. However, some IP traffic can be accepted by setting up filters.

Click Add, the following page appears. In this page, you can create a filter rule to identify incoming IP traffic by specifying a new filter name and at least one condition. All specified conditions in this filter rule must comply with the rule. Click Save/

Apply to save and activate the filter.

You should select at least one WAN interface to apply this rule.



MAC Filtering

Click Security > MAC Filtering.

MAC Filtering is only effective on ATM PVCs configured in Bridge mode. Forwarded means that all MAC layer frames are forwarded except those matching any of the specified rules in the following table. Blocked means that all MAC layer frames are blocked except those matching with any of the specified rules in the following table.

Click Change Policy and the following page will appear. Then you can change the MAC Filtering Global Policy from FORWARDED to BLOCKED.

Read the warning information. Click Yes to change the MAC filtering global policy from Forwarded to Blocked. Click No to cancel.



Parental Control

Click Security > Parental Control.

Click Add and the following page will appear.

On this page, you can add time of day restriction to a particular LAN device connected to the Router. The Browser’s MAC Address automatically displays the MAC address of the LAN device where the browser is running. To restrict other LAN device, click

Other MAC Address and enter the MAC address of the another LAN device. To obtain the MAC address of a Windows based

PC, enter ipconfig /all in the DoS window.



Quality of Service

Many communication and multimedia applications require large, high-speed bandwidths to transfer data between the local network and the internet.

However, for many applications there is often only one internet connection available with limited capacity. QoS divides this capacity between the different applications and provides undelayed, continuous data transfer in situations where data packets with higher priority are given preference.

Click Quality of Service and the following page will appear. Under Quality of Service, there are two network share modes: Queue Config and QoS

Classification.

Network QoS is an industry-wide set of standards and mechanisms for ensuring high-quality performance for critical applications. By using QoS mechanisms, network administrators can use existing resources efficiently and ensure the required level of service without reactively expanding or over-provisioning their networks.

Traditionally, the concept of quality in networks meant that all network traffic was treated equally. The result was that all network traffic received the network’s best effort, with no guarantees for reliability, delay, variation in delay, or other performance characteristics. With best-effort delivery service, however, a single bandwidth-intensive application can result in poor or unacceptable performance for all applications. The QoS concept of quality is one in which the requirements of some applications and users are more critical than others, which means that some traffic needs preferential treatment.



Enabling QoS

In this page, you can perform QoS queue management configuration. By default, the system enables QoS and sets a default DSCP mark to automatically mark incoming traffic without reference to particular classifier.

Select Advanced Setup > Quality of Service and the following page will appear.

Select Enable QoS to enable QoS and set the default DSCP mark. Click Save/Apply to activate QoS.



QoS Configuration

The queuing in packet QoS goes into effect only when a packet is forwarded to a QoS-enabled PVC. Packet forwarding is determined by IP routing or bridging, not under control of the packet QoS.

Click Queue Config, and the following page will appear. In this page, you can configure QoS queue. A maximum of 16 entries can be configured.

QoS Queue Configuration can allocate four queues. Each of the queues can be configured for a precedence value (Lower integer values for precedence imply higher priority for this queue relative to others). The queue entry configured is used by the classifier to place ingress packets appropriately.

Note: Lower integer values for precedence imply higher priority for this queue relative to others.

For example, add a QoS queue entry and allocate it to a specific network interface (PVC 0/0/35). Set integer values for queue precedence to 1.



Step 1

Click Add, and the following page will appear.

Queue Configuration Status: set to enable or disable a QoS queue.

Queue: Select a specific network interface. When you have already selected a network interface, the specific network interface selected automatically allocates to the queue.

Queue Precedence: Select an integer value for queue precedence. After you select an integer value, the queue entry appropriately places to ingress packets. Lower integer values for precedence imply higher priority for this queue relative to others.

Step 2

Add a QoS queue entry and assign it to a specific network interface (PVC 0/0/35), and set integer values for queue precedence to 1. See the following figure:

Step 3

After proper modifications, click Save/Apply and the following page will appear. This configuration takes effect immediately.

To delete a certain queue, disable it, select it, and then click Remove. After the queue is configured, you can create several traffic class rules to classify the upstream traffic.



QoS Classification

Some applications require specific bandwidth to ensure its data be forwarded in time. QoS classification can creates traffic class rule to classify the upstream traffic. Assign queue which defines the precedence and the interface and optionally overwrite the IP header DSCP byte. After QoS classification, QoS divides capacity between different applications and provides undelayed, continuous data transfer where data packet with higher priority is given preference.

Click QoS Classification and the following page will appear.

In this page, you can configure network traffic classes.

Click Add to continue.



Traffic Class Name: Enter a name of the class.

Rule Order: Select order for queue.

Rule Status: Enable or disable this traffic class rule.

Assign Classification Queue: Select a classification queue.

Assign Differentiated Service Code Point (DSCP) Mark:

Select a mark service that modifies the original packet IP header if all rules defined within the classification class are matched.(CS-Mark IP Precedence, AF-Assured Forwarding,

EF-Expedited

Forwarding)

Mark 802.1p if 802.1q is Enabled: Select an 802.1p priority number that serves as the 802.1p value.

There are two sets of classification rules. Set-1 is based on different fields within TCP/UDP/IP layer plus physical LAN port. Set-2 is based on MAC layer IEEE 802.1p priority field.

Set-1 Rules contain the following:

Physical LAN Port: Select one among Ethernet ports and


Section 9 - Advanced Setup wireless port.

Protocol: Select one among TCP/UDP TCP UDP or ICMP protocols.

Source IP Address

Source Subnet Mask

UPD/TCP Source Port

Destination IP Address

Destination Subnet Mask

UPD/TCP Destination Port or a Range of Ports

Source Mac Address

Source Mac Mask

Destination Mac Address

Destination Mac Mask

Set-2 Rules contain the following:

802.1p Priority: the 802.1p header includes a 3-bit prioritization field, which allows packets to be grouped into eight levels of priority (0-7), where level 7 is the highest one.



QoS-DSCP Setting

In order to understand Differentiated Services Code Point (DSCP), you should be familiar with the differentiated services model (Diffserv).

Diffserv is a Class of Service (CoS) model that enhances best-effort Internet services by differentiating individual user traffic, service requirements and other criteria. Packets are specifically marked, allowing network nodes to provide different levels of service via priority queuing or bandwidth allocation, or by choosing dedicated routes for specific traffic flows.

As displayed in following diagram, the IPV4 packet has a TOS field. Diffserv defines TOS field in IP packet headers referred to as DSCP. Hosts or routes that pass traffic to a Diffserv-enabled network typically mark each transmitted packet with an appropriate DSCP. The DSCP markings are used by Diffserv network routers to appropriately classify packets and to apply particular queue handing or scheduling behavior.

Section 12 - Troubleshooting

Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DSL-520B. Read the following descriptions if you are having problems. (The examples below are illustrated in Windows ® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples.)

1. Why can’t I access the web-based configuration utility?

When entering the IP address of the D-Link modem (192.168.1.1 for example), you are not connecting to a website on the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.

• Make sure you have an updated Java-enabled web browser. We recommend the following:

• Internet Explorer 6.0 or higher

• Firefox 3.0 or higher

• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on.

• Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows ® XP firewall may block access to the configuration pages. Check the help files included with your firewall software for more information on disabling or configuring it.


Section 12 - Troubleshooting

• Configure your Internet settings:

• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults.

• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked. Click OK.

• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.

• Close your web browser (if open) and open it.

• Access the web management. Open your web browser and enter the IP address of your D-Link modem in the address bar. This should open the login page for your the web management.

• If you still cannot access the configuration, unplug the power to the modem for 10 seconds and plug back in. Wait about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.

2. What can I do if I forgot my password?

If you forgot your password, you must reset your modem. Unfortunately this process will change all your settings back to the factory defaults.

To reset the modem, locate the reset button (hole) on the rear panel of the unit. With the modem powered on, use a paperclip to hold the button down for 10 seconds. Release the button and the modem will go through its reboot process. Wait about 30 seconds to access the modem. For information about logging into the modem see page 16.


Appendix A - Networking Basics

Networking Basics

Check your IP address

After you install your new D-Link device, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless modem) automatically. To verify your IP address, please follow the steps below.

Click on Start > Run. In the run box type cmd and click OK.

At the prompt, type ipconfig and press Enter.

This will display the IP address, subnet mask, and the default gateway of your adapter.

If the address is 0.0.0.0, check your device installation, security settings, and the settings on your modem. Some firewall software programs may block a DHCP request on newly installed device.

If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network settings.

Check your MAC address

Click on Start > Run. In the run box type cmd and click OK.

At the prompt, type ipconfig /all and press Enter.

This will display information about all installed adapters on your computer. Your MAC address is listed as the “Physical Address” and should look like xx-xx-xx-xx-xx-xx or xx:xx:xx:xx:xx:xx


Appendix A - Networking Basics

Statically Assign an IP address

If you are not using a DHCP capable gateway/modem, or you need to assign a static IP address, please follow the steps below:

Step 1

Windows ® XP - Click on Start > Control Panel > Network Connections.

Windows ® 2000 - From the desktop, right-click My Network Places > Properties.

Step 2

Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.

Step 3

Highlight Internet Protocol (TCP/IP) and click Properties.

Step 4

Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your modem.

Example: If the modem´s LAN IP address is 192.168.1.1, make your IP address 192.168.1.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set

Default Gateway the same as the LAN IP address of your modem (192.168.1.1).

Set Primary DNS the same as the LAN IP address of your modem (192.168.1.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP.

Step 5

Click OK twice to save your settings.
