To configure Web filtering using the J-Web Configuration editor, if you are using custom objects, you must create the custom objects (URL pattern list, custom URL category list).

In addition to custom object lists, you can use included default lists and whitelist and blacklist categories.

Configure a URL Pattern List Custom Object as follows:

Because you use URL pattern lists to create custom URL category lists, you must configure URL pattern list custom objects before you configure a custom URL category list.

1. Select Configure>Security>UTM>Custom Objects.
2. From the URL Pattern List tab , click Add to create URL pattern lists.
3. Next to URL Pattern Name, enter a unique name for the list you are creating. This name appears in the Custom URL Category List Custom Object page for selection.
4. Next to URL Pattern Value, enter the URL or IP address that you want to add to list for bypassing scanning.

   URL pattern wildcard support—The wildcard rule is as follows: \*\.[]\?* and you must precede all wildcard URLs with http://. You can only use “*” if it is at the beginning of the URL and is followed by a “.”. You can only use “?” at the end of the URL. The following wildcard syntax is supported: http://*.juniper.net, http://www.juniper.ne?, http://www.juniper.n??. The following wildcard syntax is not supported: *.juniper.net , www.juniper.ne?, http://*juniper.net, http://*.

5. Click Add to add your URL pattern to the Values list box.

   The list can contain up to 8192 items. You can also select an entry and use the Delete button to delete it from the list. Continue to add URLs or IP addresses in this manner.

6. Click OK to save the selected values as part of the URL pattern list you have created.
7. If the configuration item is saved successfully, you receive a confirmation. Click OK. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Configure a custom URL category list custom object as follows:

Because you use URL pattern lists to create custom URL category lists, you must configure URL pattern list custom objects before you configure a custom URL category list.

1. Select Configure>Security>UTM>Custom Objects.
2. From the URL Category List tab, click Add to create URL category lists.
3. Next to URL Category Name, enter a unique name for the list you are creating. This name appears in the URL Whitelist, Blacklist, and Custom Category lists when you configure Web filtering global options.
4. In the Available Values box, select a URL Pattern List name from the list for bypassing scanning, and click the right arrow button to move it to the Selected Values box.
5. Click OK to save the selected values as part of the custom URL list you have created.
6. If the configuration item is saved successfully, you receive a confirmation. Click OK. If it is not saved successfully, you can click Details in the pop-up window that appears to discover why.

Now that your custom objects have been created, you can configure the integrated Web filtering feature profile.

The below steps use Surf Control Web filtering type. SRX1500 devices do not support Surf Control Integrated option. Hence replace Surf Control with Websense.

1. Select Configure>Security>UTM>Global options.
2. In the Web Filtering, next to URL whitelist, select the Custom URL list you created from the available options.

   This is the first filtering category that both integrated and redirect Web filtering use. If there is no match, the URL is sent to the SurfControl server.

   The SurfControl option is not supported on SRX1500 devices. For SRX1500 devices, the URL is sent to the Websense server.

3. Next to URL blacklist, select the Custom URL list that you have created from the list.

   This is the first filtering category that both integrated and redirect Web filtering use. If there is no match, the URL is sent to the SurfControl server.

4. In the Filtering Type section, select the type of Web filtering engine you are using.

   In this case, you would select Surf Control Integrated.

5. In the SurfControl Integrated options section, next to Cache timeout, enter a timeout limit, in minutes, for expiring cache entries (24 hours is the default and the maximum allowed life span).
6. Next to Cache Size, enter a size limit, in kilobytes, for the cache (500 KB is the default).
7. Next to Server Host, enter the Surf Control server name or IP address.
8. Next to Server Port, enter the port number for communicating with the Surf Control server (default ports are 80, 8080, and 8081).
