Limited access filters provide a very precise method of granting Internet access. Each limited access filter is a list of individual URLs, IP addresses, or regular expressions. Like category filters, limited access filters are added to policies and enforced during a specified time period. When a limited access filter is active in a policy, users assigned that policy can visit only websites in the list. All other sites are blocked.
For example, if the First Grade policy enforces a limited access filter that includes only certain educational and reference sites, students governed by the First Grade policy can visit only those sites, and no others.
When a limited access filter is active, a block page is returned for any requested URL not included in that filter.
Web protection software can support up to 2,500 limited access filters containing 25,000 URLs in total.
Limited access filters and enforcement order
When multiple group policies apply to a user, the Use most restrictive group policy setting (see Enforcement order) determines which one is used to manage the user's requests. By default, this setting is off.
Filtering Service determines which setting is less restrictive at the filter level. In cases where a user might be assigned to multiple policies, one of which is enforcing a limited access filter, "less restrictive" may sometimes seem counterintuitive.
When Use most restrictive group policy is OFF:
*
If the Block All category filter and a limited access filter could apply, the limited access filter is always considered less restrictive.
*
This means that even when the limited access filter permits the site and the category filter blocks the site, the site is blocked.
When Use most restrictive group policy is ON, a limited access filter is considered more restrictive than any category filter except Block All.
The table below summarizes how the Use most restrictive group policy setting affects policy enforcement when multiple policies could apply:
