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

67



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

mask.

Event Log

The Event Log page allows you to send firewall event log reporting to a standard SysLog

server or via email. Individual attack or configuration items can be selected that will be

sent to the SysLog server or emailed so that only the items of interest can be monitored.

Permitted connections, blocked connections, known Internet attack types, and Cable

Modem/Router configuration events can also be logged. The SysLog server must be on

the same subnet as the Private LAN behind the Cable Modem/Router (typically

192.168.0.x).
