URL Filtering Policies

HTTP > URL Filtering > Policies

Make sure that the URL filtering module is enabled before you start. The Account fields support IPv6 addresses. You can define one rule for any IPv6 host, and this policy rule is triggered when the client accesses Web sites through IWSVA.

When selecting policies, both IPv4 and IPv6 policies will appear. In the Account field, acceptable account entries include a single IPv6 address, an IPv6 range, or an IPv6 mask similar to what has been supported with IPv4.

IWSVA supports the “URL Warn mode” feature with IPv6, and can automatically redirect the warning message to IWSVA’s IPv6 or IPv4 addresses to the client based on the version of the client’s IP address.

• When a client uses an IPv4 address, IWSVA sends a redirect request with IWSVA’s IPv4 address.

• When a client uses an IPv6 address, IWSVA sends a redirect request with IWSVA’s IPv6 address.

The URL Filtering Policy list shows all policies on the system—enabled as well as disabled. Click Add to create a new policy, or click a list item to edit an existing one.  

• Enable URL filtering—Globally controls the enabled status of all policies; overrides the status of an individual policy. Click Save after enabling or disabling URL filtering.

• Enable dynamic URL categorization—Globally controls the enabled status of URL categorization. Click Save after enabling or disabling dynamic URL categorization.

• Add—Opens the Add Policy wizard that will take you through the steps of defining a new policy.

• Priority—Sets the order of precedence—if two conflicting policies overlap in their scope, the policy with the higher priority (closer to 1) will be applied and the other ignored. MORE>>

  The URL Filtering policy manager first evaluates a given Web request by finding out of which group, if any, the requesting client is a member, and then by evaluating which policy or policies are in effect for that group.

  If the client is affected by more than one policy, the policy with the highest priority is applied. No other policies in the list are evaluated for the criteria already found.

• Note 1: The URL Filtering Global Policy is the default policy. It automatically applies to all users, but also always takes the lowest priority. Any policy above it in the list will take precedence.

• Note 2: The URL Filtering Guest Policy is only enabled after certain conditions have been met. See Guest Policies for additional details.  

• Deploy Policies—Click this button after creating or modifying a URL filtering policy to have it immediately take effect.
