are:

• RIP1

• RIP2

• RIP1/2

Your selection should match the version supported by other routers on your network.
Update Interval Specify how often, in seconds, the Gateway sends routing-update messages.
Default Metric Enter a number by which the metric value for the path increases when the Gateway receives a routing

update that includes changes to an entry. Choices are 1 – 15. Default is 1.
Authentication Type Select the authentication mechanism used, if any. Choices are:

• No Authentication = no authentication is used. If you keep this default setting, the Authentication

Key & ID fields are gray and unavailable.

• Simple Password = an authentication method where a clear text pas sword is sent to participating

neighbors on the network. This selection sends the auth ent icating password over the network,
possible making it available to individuals who can access packets off the network. Do not use this
option as part of your security strategy, Rather, use it t o avoid accidental changes to the routing
infrastructure. If you select this setting, the first field in the Authentication Key & ID option becomes
available for entering the password.

• md5 = an authentication method that works much like Simple Password authenticati on, except that

MD5 does not send the key over the network. Instead, a router uses the MD 5 algorit hm to produc e
a message digest of the key (also called a hash). The router sends the message digest instead of
the key itself, which ensures that no one can eave sdrop on the network and learn keys during
transmission. If you select this setting, the first field in the Authentication Key & ID option becomes
available for entering the key and the second field becomes available for entering the ID.

Authentication Key & ID Specify the appropriate information based on the Authentication Type selected:

• No Authentication = no entry required.

• Simple Password = in the first field, enter the clear-text password to be used for authentication.

The second field requires no entry, and is gray and unavailable.

• md5 = in the first field, enter the MD5-hash password. In the second field, enter the Key Identifier

that identifies the key used to create the authentication data f or this message.

Neighbor IP Enter the IP address of the Gateway’s RIP neighbor router.

DMZ Page

Path: Advanced > DMZ

If you have a local client computer that cannot run an Internet application properly behind the firewall,
you can configure the computer for unrestricted two-way Internet access by defining it as a Virtual DMZ
host. A DMZ allows a single computer on your LAN to expose its ports to the Internet. When doing this,
the exposed computer is no longer “behind” the firewall. Therefore, placing a computer in the DMZ
should be considered temporary because the firewall is no longer able to provide any security to it.

Figure 51. DMZ Page

Table 25. DMZ Page Options

Option Description

Enable DMZ Enables or disables the Gateway’s DMZ setting.

• Enabled = Gateway’s DMZ feature is enabled.

• Disabled = Gateway’s DMZ feature is disabled. This selection makes the SMZ Host field

unavailable.

DMZ Host Enter the IP addresses of the computer to be used as the DMZ server.

QoS Page

Path: Advanced > QoS

The QoS page lets you configure the Gateway to deliver better resource reservation control. Wireless
networks offer an equal opportunity for all devices to transmit data from any type of application.
Although this is acceptable for most applications, multimedia audio and video applications are
particularly sensitive to the delay and throughput variations that result from this “equal opportunity”
wireless access method. For multimedia applications to run well over a wireless network, a Quality of
Service (QoS) mechanism is required to prioritize traffic types and provide an “enhanced opportunity”
wireless access method.

The QoS page lets you enable or disable QoS settings. After making your selections, click the SAVE
button to apply them. You can change QoS settings without having to reboot the Gateway.

Device Discovery Page

Path: Advanced > Device Discovery

Universal Plug and Play (UPnP) is an architecture that allows for dynamic connectivity between devices
on a network. The goal of UPnP is to support zero-configuration, "invisible" networking of devices
including intelligent appliances, PCs, printers and other smart devices using standard protocols.

Using UPnP, devices can add themselves to a network dynamically, without requiring user intervention
or configuration. A UPnP-enabled device 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.

Using the Device Discovery page, the Gateway can discover all UPnP-enabled devices on the network.
After making your selections, click the SAVE button to apply them.

Table 27. Device Discovery Page Options

Option Description

Enable UPnP Determines whether the Gateway’s UPnP capabilities are enabled or disabled. Choices are:

• Enabled = enables the Gateway’s UPnP capabilities.

• Disabled = disables the Gateway’s UPnP capabilities.

Advertisement Period Specify how often, in seconds, the Gateway broadcasts its UPnP information. This value can

range from 1 to 2147483648 seconds. Short durations ensure that co ntrol points have current

device status at the expense of additional network traffic. Long durations can compromise the

freshness of the device status, but can significantly reduce network traffic.
Time To Live Configure the number of hops (steps) for the advertisement time to live. The time to live for the

advertisement is measured in hops for each UPnP packet sent. The t ime to live hop count is the

number of steps a broadcast packet is allowed to propagate for each UPnP advertisement

before it disappears. The number of hops can range from 1 to 255. The default sett ing should be

fine for most home networks. If some of your devices are not being updat ed or reached

correctly, you can increase this value slightly.
