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

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).

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.

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.

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.

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

Module is disabled in the Security Settings (Firewall) menu (see page 73).

5. To configure additional triggers (up to 20), repeat steps 1 through 4. When you finish, click

Apply in the Special Applications menu to save your settings.

6. To change the settings for a trigger, click the radio button to the left of the trigger you want to change and click the Edit button. When the Trigger menu appears, edit the settings as necessary (see Table 22) and click Apply. Click Apply in the Special Application menu to save your settings.

Description

Name for identifying the trigger. The name is for reference purposes only.

The type of protocol you want to use with the trigger. Choices are TCP and UDP. Default is

TCP. For example, to track the H.323 protocol, the protocol type should be TCP.

From and To port ranges of the special application. For example, to track the H.323 protocol, the From and To ports should be 1720.

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.
