N2H2

To configure N2H2 content filtering options, complete the following steps:

1	In the left pane, select the global icon, a group, or a SonicWALL appliance.

2	Click the Policies tab

3	In the center pane, navigate to Website Blocking > N2H2.

4	Enter the N2H2 server name or IP address in the Server Host Name or IP Address field.

5	Enter the port that the N2H2 server listens for N2H2 requests in the Listen Port field (default: 4005).

6	Enter the port that the N2H2 server uses to send packets to the SonicWALL appliances in the Reply Port field (default: 4005).

7	Enter the username associated with the N2H2 account in the User Name field.

8	Enter the size of the URL cache in the URL Cache Size field. A larger URL cache can improve browser response times.

9	Select the action that the SonicWALL appliance(s) will take if the N2H2 server is unavailable beyond a specified period of time. First, enter the time period (in seconds) in the If user is unavailable for field. Then, select one of the options:

•	To block traffic to all Web sites, select Block traffic to all Web sites.

•	To allow access to all Web sites, select Allow traffic to all Web sites.

10	If a server marks a URL as blocked, select one of the following actions:

•	Block Access to URL—Blocks access to restricted sites and logs access attempts.

•	Log Access to URL—Does not block access to restricted sites, but logs access. This enables organizations to monitor appropriate usage without restricting access.

11	When you are finished, click Update. The scheduler displays.

12	Expand Schedule by clicking the plus icon.

13	Select Immediate or specify a future date and time.

14	Click Accept.
