Configuring Time Range
With this option you can configure access time range records for eventual association with ACL rules. ACL
rules associated with a time range record will be active only during the scheduled period. If the ACL rule
denies HTTP access during 10:00hrs to 18:00hrs, then before 10:00hrs and after 18:00hrs the HTTP traffic will
be permitted to pass through. One time range record can contain up to three time periods. For example:
Office hours on weekdays (Mon-Fri) can have the following periods:
„ Pre-lunch period between 9:00 and 13:00 Hrs
„ Post-lunch period between 14:00 and 18:30 Hrs
Office hours on weekends (Saturday-Sunday) can have the following periods:
„ 9:00 to 12:00 Hrs
Such varying time periods can be configured into a single time range record. Access rules can be activated
based on these time periods.
