Measuring and Limiting Traffic with the Traffic Meter
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.
STEP 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
