Monitor NAT Statistics
Network address translator (NAT) is software that runs on a PortMaster and maps one IP address or a group of IP addresses to another IP address or group of IP addresses. To check statistics for NAT sessions, click Monitor==>NAT Statistics.
Select a NAT session and use the Reset Counters button to restart incrementing values in PMVision only, not on the PortMaster. Use Restore Counters to restore these counters to their real-time values.
To view NAT Statistics simultaneously with other options in
the PMVision tree, click New Window.
