Example 5
Goal
You are an administrator of your office network. Your PCs have IP addresses, ranging 192.168.3.2-192.168.3.255. The office network is connected to the Internet by a NAT router running Microsoft Windows
Server 2003 (192.168.3.1). Your goal is to count the Internet-traffic for every PC of the office network. The traffic between the PCs within the office network must not be accounted.
Solution
You should do the following:
- Fill in the Local Address Table (LAT) with a range 192.168.3.1-192.168.3.255
- Create the filters for traffic accounting (one filter per PC)
| Filter 1. Internet traffic of PC 192.168.3.2. |

 Note
- In this example, you should not use the DHCP service to assign the IP addresses to the PCs.
- In this example, TrafMeter Service can run on a NAT router or on any PC of the office network. See topic "TrafMeter Installation Guide" for details.
- You should use Active Capture Mode on computers running NAT.
