Address

are creating an IPv4 rule this should be an IPv4 address.

If you are

creating an IPv6 rule this should be an IPv6 address.

Start/End Port

Enter the range of port numbers (start and end port) to forward. If

only a single port is desired, enter the same port number in the

Start

and

End

locations.

Protocol

Select the protocol(s) to be forwarded.

Description

A brief description of the rule you have created.

Enabled

Select ON to enable the rule. For security reasons you should leave

the rule disabled if you are not using it.

Note:

You may need to assign static IP addresses to devices on your LAN to insure that

the port forwarding you have set up will always apply to them.

Port Triggers

The Port Triggers page allows you to configure dynamic triggers to specific devices on

the LAN. This allows for special applications that require specific port numbers with

bi-directional traffic to function properly. Applications such as video conferencing, voice,

gaming, and some messaging program features may require these special settings.

Port Triggers are similar to Port Forwarding except that they are not static ports held

open all the time. With the port triggering function, the Cable Modem/Router detects

outgoing data on a specific IP port number and opens corresponding target ports for

incoming data. If no outgoing traffic is detected on the Trigger Range ports for 10

minutes, the Target Range ports will close.

To access the

Port Triggers

page:

1

Click

Advanced

in the menu bar.

2

Then click the

Port Triggers

submenu.

3

To add a new Port Triggers rule, click on the

Create

button, to add a new rule.

Figure 21 shows an example of the menu and Table 13 describes the items you can

select.

To activate a port trigger

1

2

Select the forwarding protocol(s).

3

Enter a name for your port triggering rule.

4

Check the

Enable

box to the bottom of the entry to store settings.

Description

Trigger Range

(Start / End

Port)

Enter the trigger range (starting and ending ports) of the application

for which you want to enable port triggering. The application will

send data from these ports.

Target Range

(Start / End

Port)

Enter the target range (starting and ending ports) to open for the

same application. The application will receive data on these ports.

Protocol

Select the protocol for this rule.

Select ON to enable the rule. For security reasons you should leave

the rule disabled if you are not using it.

DMZ Host

The DMZ (De-militarized Zone) Host page allows you to configure a network device (e.g.

a PC) to be exposed or visible directly to the Internet. This may be used if an application

doesn’t work with port triggers. If you have an application that won’t run properly behind

the NAT firewall, you can configure it for unrestricted two-way Internet access by defining

it as a virtual DMZ host. Adding a client to the DMZ may expose your local network to

various security risks because the client is not protected, so use this option as a last

resort.

To access the

DMZ Host

page:

1

Click

Advanced

in the menu bar.

2

Then click the

DMZ Host

submenu.

Figure 22 shows an example of the menu.

To configure DMZ settings:

1

Enter the last byte of the LAN IP address of the PC or other device on your network

that you want to configure as a DMZ host.

2

Click

Apply

.

Note:

If a specific PC is set as a DMZ Host, remember to set this back to “0” when

finished with the needed application, since this PC will be effectively exposed to the

public Internet.

Note:

You may need to assign your DMZ host a static IP address on your LAN to

insure that it will always be at that address.

RIP Setup

The RIP Setup page allows you to configure RIP (Router Information Protocol)

parameters. RIP automatically identifies and uses the best known and quickest route to

any given destination address to help reduce network congestion and delays.

RIP is a protocol that requires negotiation from both sides of the network (e.g. both the

Cable Modem/Router and your service provider’s CMTS (Cable Modem Termination

System)). Your service provider will normally set this up based on their knowledge of

their CMTS settings.

To access the

RIP Setup

page:

1

Click

Advanced

in the menu bar.

2

Then click the

RIP Setup

submenu.

Figure 23 shows an example of the menu and Table 14 describes the items you can

select.

Figure 23. Example of RIP Setup Page

Note:

RIP messages will only be sent when the Cable Modem/Router is configured for Static IP

Addressing (see the

Basic – Setup

page).

It is unlikely that your cable Internet service supports this mode. If they do, and you want

to enable RIP, you will need to ask for the CMTS’s key name and number. You may need

additional information.

To enable the Cable Modem/Router to perform RIP, do the following (this example uses

BRCMV2 as the RIP Authentication Key and 1 as the Key ID):



To turn on RIP, check the Enable box.



To turn on RIP MD5 Authentication, and check the

Enable

box.



To specify a RIP MD5 Authentication Key String, type

BRCMV2

for this example.

key name = a string value to match CMTS key name value



To specify a RIP MD5 Auth Key ID, type

1

.

key number = a number to match the CMTS key number value



To change the RIP announcement interval, enter a number in seconds.

reporting interval by default = 30 seconds



To specify a RIP unicast destination IP address, enter the IP address and subnet

mask.
