Description

Configures your Gateway as a uPnP Internet gateway. UPnP allows for dynamic connectivity between devices on a network. A UPnP-enabled device like your Gateway can obtain an IP address, advertise its capabilities, learn about other connected UPnP devices and then communicate directly with those devices. The same device can end its connection cleanly when it wishes to leave the UPnP community. The intent of UPnP is to support zeroconfiguration, "invisible" networking of devices including intelligent appliances, PCs, printers, and other smart devices using standard protocols.

• Check = uPnP is enabled on the Gateway. (default)

• Uncheck = uPnP is disabled on the Gateway.

Configures your Gateway as a HNAP device. HNAP allows your Gateway to be configured and managed by remote entities, such as Network Magic or any software application that discovers and manages network devices.

• Check = HNAP is enabled on the Gateway. . (default)

• Uncheck = HNAP is disabled on the Gateway

LAN Settings Menu

IP addresses are close to being used up and thus very hard to get. One solution to this problem is "private" IP addresses. Private IP addresses are ranges of IP addresses set aside expressly for use by a company or other entity internally. Private IP addresses are non-routable and, therefore, cannot be used to connect directly to the Internet.

Some of the advantages of private IP addresses include: y y

Increased security, since private IP addresses are not routable across the Internet

You conserve the world-wide pool of IP addresses y You do not have to register or pay for these IP addresses in any way

Using the LAN Settings menu, you can define private LAN IP addresses. To access the LAN

Settings menu, click LAN in the menu bar. Figure 20 shows an example of the menu and

QoS Settings Menu

Quality of Service (QoS) refers to a collection of techniques for identifying data whose delivery across the network is time sensitive, and managing its delivery through both bandwidth allocation and prioritization schemes

Using the QoS Settings menu, you can enable the Gateway’s QoS module to provide guarantees on the ability of the network to deliver predictable results. To access the QoS menu, click QOS in the menu bar. Figure 23 shows an example of the menu.

By default, QoS is enabled. To disable the Gateway’s QoS module, uncheck Enable QOS

Module and click Apply. To disable the Gateway’s QoS module, uncheck Enable QOS

Module and click Apply.

When the Gateway’s QoS module is enabled, the following submenus appear under QOS in the menu bar: y y

Port - lets you configure the priority queue to which the switch port is mapped. See page

45.

COS - lets you define four queues to which the CoS is mapped. See page 46. y y y

DSCP - lets you define the QoS class queue to which the customized DSCP is mapped.

See page 48.

Queue - lets you specify whether QoS behavior runs with strict or weighted priority. See page 50.

DSCP Remarking - lets you define the DSCP remarking action and mode. See page 52.

Figure 23. QoS Settings Menu

Port Based QoS Menu

The Port Based QoS menu lets you enable or disable the Gateway’s port-based QoS setting. To access the Port Based QoS menu, click QOS in the menu bar and then click the

Port submenu in the menu bar. Figure 24 shows an example of the menu. y y

To enable the Gateway’s port-based QoS setting, check Enable Port Based QoS and click Apply.

To disable the Gateway’s port-based QoS setting, uncheck Enable Port Based QoS and click Apply.

Note: The Port submenu is not available in the menu bar if Enable QOS Module is not checked in the QoS Settings menu (see page 39).

Figure 24. Port Based QoS Menu

45



CoS Settings Menu

Given that there will always be points in the network where multiple traffic streams merge or where network links will change speed and capacity, it is important to move traffic on the basis of relative importance. Without CoS prioritization, less important traffic can consume network bandwidth and slow down or halt the delivery of more important traffic. For example, without CoS, most traffic received by the Gateway is forwarded with the same priority it had upon entering the Gateway. In many cases, such traffic is ‘‘normal’’ priority and competes for bandwidth with all other normal-priority traffic, regardless of its relative importance to your requirements. CoS helps to keep the most important network traffic moving at an acceptable speed, regardless of current bandwidth usage. This means you can manage available bandwidth so that the switch transmits the most important traffic first.

The CoS Settings menu lets you configure a CoS priority of 0 through 7 for an outbound packet. When the packet is then sent to a port, the CoS priority determines which outbound queue the packet uses. After configuring CoS priority for outbound packets, use this menu to map the classes of service to the Gateway’s four ports.

To access the CoS Settings menu, click QOS in the menu bar and then click the CoS submenu in the menu bar. Figure 25 shows an example of the menu.

Note: The COS submenu is not available in the menu bar if Enable QOS Module is not checked in the QoS Settings menu (see page 39).

Figure 25. CoS Settings Menu

46



To define CoS settings:

1. Check Enable QoS Class based on CoS.

2. For each class of service, assign a queue number from 0 to 3. Higher priority values are evaluated as being of higher importance than lower priority values.

3. Under Port Default CoS, map the Gateway’s four ports to the classes of service you defined in the previous step.

– CoS setting from 0 to 3 = normal priority. Packets in this queue leave the port after the high-priority queue is emptied.

– CoS setting from 4 to 7 = high priority. Packets in this queue leave the port first.

4. Click Apply.

47



DSCP Based QoS Menu

The DSCP Based QoS menu lets you classify and prioritize traffic using DSCP tags. DSCP allows the Gateway to determine how traffic classes should be prioritized. Using the DSCP

Based QoS menu, you can use DSCP to provide different levels of service to conforming and non-conforming traffic by appropriately selecting the DSCP values in this menu. The

Gateway uses the Hierarchical Token Bucket queuing algorithm, which divides the 64 possible DSCP code values into 8 queues.

Table 7 shows the actual queuing.

To define DSCP-based QoS settings:

1. Check Enable DHCP Based QoS.

2. For each index, enter a DSCP value from 0 to 63.

3. Under Queue, select a queue (from 0 to 3) you want to map to this DSCP value. Higher priority values are evaluated as being of higher importance than lower priority values.

4. To define DSCP-based QoS values for other queues, repeat steps 2 and 3.

5. Click Apply.

49



Queue Settings Menu

The Queue Settings menu lets you configure QoS behavior as either strict priority or weighted priority. y Strict priority – allows delay-sensitive data such as voice to be sent before packets in other queues. y Weighted priority – lets you assign each queue with a certain weight indicating the amount of guaranteed capacity, with high priority packets served before any low priority packets.

To access the Queue Settings menu, click QOS in the menu bar and then click the Queue submenu in the menu bar. Figure 27 shows an example of the menu.

Note: The Queue submenu is not available in the menu bar if Enable QOS Module is not checked in the QoS Settings menu (see page 39).

Figure 27. Queue Settings Menu

By default, the Gateway uses strict priority. To change to weighted priority:

1. For Queue Type, select Weighted Priority. The options in Figure 28 appear.

Figure 28. Weighted Priority Options

2. For Weight Base, select a queue weight to ensure that some sets of queues get higher thresholds than others. Queue weight directs the Gateway to set the queue thresholds proportionately. Choices are 8 or 10. Queues with a weight of 10 are longer than those with a queue weight of 8.

3. For each Gateway queue, enter a weight. Each weight corresponds to a percentage of consumed bandwidth, as shown in the % of Bandwidth column.

Dscp remarking mode Lets you select the DSCP remarking mode that the Gateway is to use. Choices are:

• Map frame priority to AF code points = select this option for Quality of Service configurations that use assured forwarding (AF) code points to mark packets. AF guarantees a certain amount of bandwidth to an AF class and allows access to extra bandwidth, if available. (default)

• Map frame priority to CS code points = select this option for Quality of Service configurations that use class selector (CS) code points to mark packets. CS provides code points that can be used for backward compatibility with IP Precedence. IP Precedence is a legacy technology that the Gateway supports for backwards compatibility.

Request a remarking action when DSCP equals one of the following CPs

Others

Expedited forwarding provides a low-loss, low-latency, low-jitter, and assured bandwidth service.

Applications such as VoIP, video, and other time sensitive applications require a robust network treatment like expedited forwarding. When checked, the Gateway requests a remarking action if DSCP equals an expedited forwarding code point. By default, this option is not checked.

Assured forwarding defines a method by which packets can be given different forwarding assurances.

Traffic can be divided into different classes and then each class given a certain percentage of bandwidth.

For example, one class could have 50% of the available link bandwidth, another class could have 30%, and another 20% of the bandwidth. When checked, the Gateway requests a remarking action if DSCP equals an assured forwarding code point. By default, this option is not checked.

Class Selector code points are code points that can be used for backward compatibility with IP Precedence models. When checked, lets the Gateway request a remarking action if DSCP equals a class selector code point. By default, this option is checked, but does not take effect until the OSPF Status changes to

ENABLE.

When checked, lets the Gateway request a remarking action if DSCP equals zero. By default, this option is checked, but does not take effect until the OSPF Status changes to ENABLE.

When checked, lets the Gateway request a remarking action if DSCP equals a non-zero value. By default, this option is checked, but does not take effect until the OSPF Status changes to ENABLE.

WPS Setup

Using the WPS Setup menu, you can enable or disable WPS. WPS is a standard for easy and secure wireless network set up and connections.

The advantages of WPS are: y WPS automatically configures the network name (SSID) and WPA security key for the

Gateway and for the access point and wireless devices that join the network. y y

You do not need to know the network name and security keys or passphrases to use

WPS to join a wireless network.

No one can guess your security keys or passphrase because they are generated randomly. y WPS uses the Extensible Authentication Protocol (EAP), which is a strong authentication protocol used in WPA2.

The disadvantages of WPS are: y y y

Unless all the Wi-Fi devices on the network are WPS-compatible, you cannot take advantage of the ease of securing the network.

Not all wireless equipment supports WPS.

If your wireless devices do not support WPS, it can be hard to join a network that was set up with WPS because the wireless network name and security key are random sequences of letters and numbers.

To access the WPS Setup menu, click Wireless in the menu bar and then click the WPS submenu. Figure 34 shows an example of the menu. Using the WPS Config drop-down list, select the appropriate option to enable or disable WPS setup.

MAC Filtering

Using the MAC Filtering menu, you can define up to 16 MAC address filters to prevent PCs from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This is useful because a specific NIC’s MAC address never changes, unlike its IP address, which can be assigned by a DHCP server or hard-coded to various addresses over time.

The MAC Filtering menu allows wireless client stations to connect over a wireless connection in two ways: y y

By allowing all wireless station access.

By allowing only trusted PCs.

To access the MAC Filtering menu, click Wireless in the menu bar and then click the MAC

Filtering submenu. Figure 36 shows an example of the menu and Table 14 describes the settings you can select.

Configuring Special Applications

Using the Special Application menu, you can configure the Gateway to detect port triggers for detect multiple-session applications and allow them to pass the firewall. For special applications, besides the initial communication session, there are multiple related sessions created during the protocol communications. Normally, a normal treats the triggered sessions as independent sessions and blocks them. However, the Gateway can co-relate the triggered sessions with the initial session and group them together in the NAT session table. As a result, you need only specify which protocol type and port number you want to track, as well as some other related parameters. In this way, the Gateway can pass the special applications according to the supplied information.

Assume, for example, that to use H.323 in a Net Meeting application, a local client starts a session A to a remote host. The remote host uses session A to communicate with the local host, but it also could initiate another session B back to the local host. Since there is only session A recorded in the NAT session table when the local host starts the communication, session B is treated as an illegal access from the outside and is blocked. Using the Special

Application menu, you can configure the Gateway to co-relate sessions A and B and automatically open the port for the incoming session B.

To display the Special Applications menu, click Firewall in the menu bar and then click the

Special Application submenu. Figure 47 shows an example of the menu.

The maximum number of allowed triggers is 20. To enable the special application function, check the Enable Triggering checkbox and click Apply. To disable it, uncheck the Enable

Triggering checkbox and click Apply.

Note: The Special Application submenu is not available in the menu bar if Enable Firewall

From and To port ranges for the target port listening for the special application.

Specify the interval between 50 and 30000 between two continuous sessions. If the interval exceeds this time interval setting, the sessions are considered to be unrelated.

Select the IP replacement according to the application. Some applications embed the source host's IP in the datagram and normal NAT would not translate the IP address in the datagram.

To make sure the network address translation is complete, IP replacement is necessary for these special applications, such as H.323.

Decide whether the sessions can start from/to a third host. To prevent hacker attacks from a third host, this feature usually is not allowed. However, for some special applications, such as

MGCP in a VOIP application, a session initiated from a third host is permitted. For example, assume Client A is trying to make a phone call to a host B. Client A tries to communicate with the Media Gateway Controller (MGC) first and provides host B's number to MGC. Then MGC checks its own database to find B and communicate with B to provide B the information about

A. B uses this information to communicate directly to A. So initially, A is talking to MGC, but the final step has B initiating a session to A. If the third-party host-initiated session is not allowed in this example, the whole communication fails.

Configuring URL Blocking

Using the URL Blocking menu, you can configure the Gateway to block access to certain

Web sites from local computers by entering either a full URL address or keywords of the

Web site. the Gateway examines all the HTTP packets to block the access to those particular sites. This feature can be used to protect children from accessing inappropriate

Web sites. You can block up to 50 sites.

Using URL blocking, you can also make up to 10 computers exempt from URL blocking and have full access to all Web sites at any time.

To display the URL Blocking menu, click Firewall in the menu bar and then click the URL

Blocking submenu. Figure 49 shows an example of the menu.

Note: The URL Blocking submenu is not available in the menu bar if Enable Firewall

Figure 50. Schedule Rule Menu

By default, the Gateway is configured to apply schedule rules to URL blocking 24 hours every day. To change these settings:

1. To change the days when schedule rules are applied to URL blocking, uncheck Every Day under Week Day. Then check the days when you want to apply schedule rules to URL blocking.

2. To change the hours when schedule rules are applied to URL blocking, uncheck All Day.

Then specify the start and end times when you want to apply schedule rules to URL blocking. Select AM or PM, where AM refers to times from Midnight to Noon and PM refers to times from Noon to Midnight.

3. Click Apply.

92



Configuring Email and Syslog Alerts

The Gateway inspects packets at the application layer, and stores TCP and UDP session information, including timeouts and number of active sessions. This information Is helpful when detecting and preventing Denial of Service (DoS) and other network attacks.

If you enabled the Gateway’s firewall or content-filtering feature, you can use the

Email/Syslog Alert menu to configure the Gateway to send email notifications or add entries to the syslog when: y y

Traffic is blocked

Attempts are made to intrude onto the network y Local computers try to access block URLs

You can configure the Gateway to generate email notifications or syslog entries immediately or at a preconfigured time.

To access the Email/Syslog Alert menu, click Firewall in the menu bar and then click the

Email/Syslog Alert submenu in the menu bar. Figure 51 shows an example of the menu.

The menu has three sections: y y

The top area lets you configure the Gateway to send email notifications.

The middle area lets you configure the to add syslog entries. y The bottom area lets you define the alerting schedule.

Note: The Email/Syslog Alert submenu is not available in the menu bar if Enable Firewall

94



Configuring Email Alerts

The following procedure describes how to configure the Gateway to send email notifications.

This procedure assumes that your mail server is working properly.

1. In the Email/Syslog Alert menu, under Mail Server Configuration, enter the following information:

– SMTP Server Address = IP address of the SMTP server that will forward the email notification to recipients.

– Sender’s Email Address = name that will appear as the sender in the email notifications.

2. Under Mail Server Authentication, enter the following information:

– User Name = your email name.

– Password = your email password.

3. Under Recipient list, click Add. When the Recipient Adding menu appears (see Figure

52), enter the name of the person who will receive email notifications and the person’s email address, and then click Apply. (Or click Back to return to the Email/Syslog Alert menu or Cancel to cancel any selections you made.) If you clicked Apply, the email account is added to the Recipient list. To send email to additional email accounts (up to

4), repeat this step.

4. To change the settings for an email recipient, click the radio button to the left of the recipient you want to change and click the Edit button. When the Recipient Adding menu appears, edit the settings as necessary and click Apply.

5. To delete an email recipient, click the radio button to the left of the recipient and click

Delete. No precautionary message appears before you delete the email recipient.

6. Click Apply.

Configuring Syslog Entries

To have the Gateway add a syslog entry when traffic is blocked, attempts are made to intrude onto the network, or local computers try to access blocked URLs:

1. In the Email/Syslog Alert menu, under Syslog Server Configuration, enter the syslog server address.

2. Click Apply.

Configuring Alert Options

Using the options in the Alert Options area, you can configure the Gateway to send an email to recipients you define in this menu and/or send entries to a syslog defined in this menu if the Gateway detects an intrusion.

To configure the Gateway to send an email to the configured email addresses if it detects an intrusion:

1. Perform steps 1 through 3 under “Configuring Email Alerts” on page 95.

2. Under Alert Options, check Send Email next to When intrusion is detected.

3. Click Apply.

To configure the Gateway to send an entry to a syslog if it detects an intrusion:

1. Perform step 1 under “Configuring Syslog Entries” on page 96.

2. Under Alert Options, check Send Syslog next to When intrusion is detected.

4. Click Apply.

96



Configuring DMZ Settings

If you have a local client computer that cannot run an Internet application properly behind the NAT firewall, you can configure it for unrestricted two-way Internet access by defining it as a Virtual Demilitarized Zone (DMZ) host. Adding a client to the DMZ may expose your local network to various security risks because the client in the DMZ is not protected by the firewall.

To access the DMZ (Demilitarized Zone) menu, click Firewall in the menu bar and then click the DMZ submenu in the menu bar. Figure 53 shows an example of the menu.

Note: The DMZ submenu is not available in the menu bar if Enable Firewall Module is disabled in the Security Settings (Firewall) menu (see page 73).

Figure 53. DMZ (Demilitarized Zone) Menu

To configure DMZ settings:

1. In the DMZ (Demilitarized Zone) menu, check Enable DMZ Host. The 2 rightmost fields next to this option become available.

2. Enter the last two octets in the IP addresses of the computer to be used as the DMZ server.

3. Click Apply.

97



Using the Tools Settings Menu

Using the Tools Settings menu, you can reset the Gateway and restore the device’s factory default settings. To access the Tools Settings menu, click Tools in the menu bar. Figure 54 shows an example of the menu.

Note: To reboot the Gateway and retain any customized settings, use the Reboot menu (see

“Using the Reboot Menu to Reboot the Gateway“ on page 99).
