Procedure

2. Click Network Configuration > SIP Firewall.
3. On the Firewall Configuration screen, under Rules, click New.
4. Under General, specify the following options:
• Enabled—Select or clear the check box to enable or disable this rule for the
selected Session Manager.
• Name—Name of the rule. The name can have a maximum of 80 characters.
• Action Type—Specify the action to be taken if rule conditions are met. The

through the SIP Firewall.

certain period, block the matching SIP packets for the duration of timeout
(as defined by the Threshold parameters).
- Rate Limit—If the packets matching the rule exceed a certain count in a
certain period, drop the additional matching SIP packets for the duration
of remaining period (as defined by the Threshold parameters).
Log Type—Specify if a log is to be generated or not, and if an alarm should be
sent. You must specify Log Type when the Action Type is None.
Log Message—Specify the log message to display if Log Type is set to Yes or
Alarm.
5. Under IP Layer Match Options, specify the following:
• Protocol—Select a protocol if you want the rule to be used for a specific
