Step 10 Enter any comments to help identify the access rule in the Comments field.
Step 11 The Allow Fragmented Packets check box is enabled by default. Large IP packets are often

destination host. One reason to disable this setting is because it is possible to exploit IP
fragmentation in Denial of Service (DoS) attacks.
Step 12 Click on the Advanced tab.
Step 13 If you would like for the access rule to timeout after a period of TCP inactivity, set the amount
of time, in minutes, in the TCP Connection Inactivity Timeout (minutes) field. The default

Step 14 If you would like for the access rule to timeout after a period of UDP inactivity, set the amount
of time, in minutes, in the UDP Connection Inactivity Timeout (minutes) field. The default
value is 30 minutes.

allowed by the SonicWALL security appliance in the Number of connections allowed (% of

on page 612 for more
