WEB FILTER SETTINGS

Subnets Tab

SUBNETS TAB

You can help your Web Filter server work more efficiently by using the Subnets tab to help balance the load.

Figure 9-4 Subnets tab

The Subnets tab has two sections.

•Subnet Monitoring

These settings help balance the load on your Web Filter service.

•Ignore Subnets

These settings shows the internal subnets that are detected during installation to help balance the load on the server. These subnets are not monitored.

SUBNET MONITORING

The Subnet Monitoring section is used to identify which parts of your network should be monitored or not by each Web Filter server. How you decide on this, depends on whether you have single or multiple Web Filter servers, and how you want to divide the network volume load of traffic between those servers. To configure your subnets on a single Web Filter server:

1Identify the external traffic subnets you do not want to monitor.

2Click the Subnets tab, and click Add.

3Enter the IP address of the subnet in the IP Address text box.

4Enter the subnet mask in the Mask text box.

5Click OK.
