Local Address Table (LAT)

LAT should contain all IP addresses of your Local Area Network (LAN).
 
With LAT, it is possible to create rules that will not count the traffic between hosts in your LAN. After having formulated LAT, you can refer to the addresses listed in LAT as "IP addresses of my LAN" and to the addresses not listed in LAT as "IP addresses of WAN" in the rules.

If LAT is blank, all IP addresses will be considered as "IP addresses of WAN". The maximum number of LAT records is unlimited. TrafMeter performance doesn't depend on number of records in LAT because TrafMeter uses fast algorithm for searching address inside LAT.

LAT must not contain overlapped ranges of IP addresses pairs.

Importing LAT

The IP addresses can be imported into LAT from an external plaintext file. Each string should contain one pair of IP addresses (the start IP address and the end IP address) separated by space. The example of such plaintext file is shown below:

192.168.1.1 192.168.1.255
192.168.50 192.168.5.255
192.168.80.2 192.168.80.63
