8. RIP (Routing Information Protocol) Setup
This feature enables the gateway to be used in small business situations where more than one LAN (local
area network) is installed.
The RIP protocol provides the gateway a means to ―advertise‖ available IP
routes to these LANs to your cable operator, so packets can be routed properly in this situation.
Your cable operator will advise you during installation if any setting changes are required here.

3. Local Log and Remote Log
The gateway builds a log of firewall blocking actions that Firewall has taken. Using the Local Log page
lets you specify an email address to which you want the gateway to email this log. You must also tell the
gateway your outgoing (i.e. SMTP) email server’s name, so it can direct the email to it. Enable Email
Alerts has the gateway forward email notices when Firewall protection events occur. Click
E-mail Log
to
immediately send the email log. Click
Clear Log
to clear the table of entries for a fresh start.
The log of these events is also visible on the screen. For each blocking event type that has taken place
since the table was last cleared, the table shows Description, Count, Last Occurrence, Target, and Source.

The Remote Log page allows you to specify the IP address where a SysLog server is located and select
different types of firewall events that may occur. Then, each time such an event occurs, notification is
automatically sent to this log server.
