Figure 20. Example of DMZ Host Page
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 21 shows an example of the menu and Table 15 describes the items you can select.

Figure 21. 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 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.
