Configuring Time Ranges
Fields
• Name—Specifies the name of the time range.
• Start Time—Specifies when the time range begins.
• End Time—Specifies when the time range ends.
• Recurring Entries—Specifies further constraints of active time of the range within the start and stop
time specified.
Add/Edit Time Range
The Configuration > Global Objects > Time Ranges > Add/Edit Time Range dialog box lets you define
specific times and dates that you can attach to an action. For example, you can attach an access list to a
time range to restrict access to the adaptive security appliance. The time range relies on the system clock
of the adaptive security appliance; however, the feature works best with NTP synchronization. For
detailed steps on adding a time range to an IPv6 ACL, see the “Configuring Access Rules” section on
page 30-7.
Adding a Time Range to an Access Rule
You can add a time range to an ACL to specify when traffic can be allowed or denied through an
interface.
To add a time range to an ACL, perform the following steps:
Step 1 Choose Configuration > Firewall > Access Rules.
Step 2 Choose the access list type by clicking the IPv4 Only, the IPv6 Only, or the IPV6 and IPv6 radio
button.
Step 3 Click Add. The Add Access Rule window appears.
Step 4 From the Interface drop down list, choose the desired interface.
The management interface is for management only and cannot be used to configure an access rule.
Step 5 Click Permit or Deny to permit or deny the action.
Step 6 In the Source field, enter an IP address.
Step 7 In the Destination field, enter an IP address.
Step 8 Select the service type.
Step 9 Click More Options to expand the list.
Step 10 To the right of the Time Range drop down list, click the browse button.
The Browse Time Range window appears.
Step 11 Click Add.
The Add Time Range window appears.
Step 12 In the Time Range Name field, enter a time range name, with no spaces.
Step 13 Choose the Start Time and the End Time by doing one of the following:
a. Allow the default settings, in which the Start Now and the Never End radio buttons are checked.
b. Apply a specific time range by clicking the Start at and End at radio buttons and selecting the
specified start and stop times from the lists.
