About the TCP/UDP IP Filter<br />

Advanced tab<br />

7-18 Creating Rules and Groups<br />

The IP Filter Advanced tab for TCP/UDP rules allows you to configure<br />

timeout information, stateful inspection, and control and error<br />

responses for TCP or UDP packets. Follow the steps below.<br />

Note: Stateful Packet Inspection is not currently supported for ICMP IP Filter rules in IPv4.<br />

1. To enable stateful inspection for this rule, select the Stateful Packet<br />

Inspection check box. You will not be able to configure other fields in<br />

this tab without this option selected. To disable stateful packet<br />

inspection, deselect the Stateful Packet Inspection check box.<br />

2. [TCP only] In the Connection Timeout field, specify the amount <strong>of</strong> time<br />

(in seconds) that a TCP session will wait for a connection to be<br />

established once it is started. Valid values are 1–65535. (The minimum<br />

value is one second.)<br />

3. In the Idle Timeout field, specify the amount <strong>of</strong> time (in seconds) that a<br />

session will remain open when there is no new traffic within an<br />

established session. Valid values are 1–65535. (The minimum value is<br />

one second.)<br />

4. [TCP only] In the Limit Connection Rate area, you can limit the number<br />

<strong>of</strong> connections that will be allowed per second by selecting Yes, and<br />

entering the number <strong>of</strong> connections that you want allowed per second<br />

in the Rate field. Valid values are 0—1000000000.<br />

To disable connection rate limitations, select No.
