Use the Networking > WAN > Traffic Metering pages to measure and limit traffic routed by the security appliance. If you enabled a secondary WAN link, use the navigation tree to choose either Primary WAN Metering or Secondary WAN Metering.
1. In the Traffic Meter area, enter the following information:
• Enable: Click On to enable traffic metering on the port, or click Off to disable it. Enabling this feature on the port will keep a record of the volume of traffic going from this port.
• Traffic Limit: Specify the restriction on the volume of data being transferred through the port.
– No Limit: The default option, where no limits on data transfer are imposed.
– Download Only: Limit the amount of download traffic. Enter the maximum allowed data in Megabytes that can be downloaded for a given month in the Monthly Limit field. After the limit is reached, no traffic is allowed from the WAN side.
– Both Directions: Calculate traffic for both upload and download directions. The traffic limit entered into the Monthly Limit field is shared by both upload and download traffic. For example, for a 1 GB limit, if a 700 MB file is downloaded then the remaining 300 MB must be shared between both upload and download traffic. The amount of traffic downloaded will reduce the amount of traffic that can be uploaded and vice-versa.
• Monthly Limit: Enter the volume limit that is applicable for this month. This limit will apply to the type of direction (Download Only or Both Direction) selected above. The value of zero (0) indicates that all traffic through this port will be blocked.
2. In the Traffic Counter area, enter the following information:
• Traffic Counter: Specify the action to be taken on the traffic counter.
– Restart Now: Choose this option and then click Save to reset the counter immediately.
– Specific Time: Choose this option if you want the counter to restart at a specified day and time. Then enter the time in hours (hh) and minutes (mm) and select the day of the month in the Reset Time area.
• Send Email Report: Click On to send an alert email to the specified email address before the traffic counter is reset, or click Off to disable it. This feature requires that you enable the Traffic Meter Alert feature and configure the email server settings on the Email Alert Settings page. See Configuring Email Alert Settings, page 340.
3. In the When Limit is Reached area, specify the action when the traffic limit is reached.
• Traffic Block: Choose one of the following options:
– All Traffic: Block all traffic through the WAN port when the traffic limit is reached.
– All Traffic Except Email: Block all traffic except email through the WAN port when the traffic limit is reached.
• Email Alert: Click On to send an alert email to the specified email address when the traffic limit is reached, or click Off to disable it. This feature requires that you enable the Traffic Meter Alert feature and configure the email server settings on the Email Alert Settings page. See Configuring Email Alert Settings, page 340.
