====== NAT Flow Configuration ======
{{indexmenu_n>6}}

There are 3 ways to generate a NAT log in QoE Stor (statistics server)  \\ 
1. Receive NAT Flow in a separate flow with DPI. To do this, you need to configure the DPI on the device [[en:dpi:opt_cgnat:log:start#export_nat_flows_in_ipfix_netflow_10|export of broadcasts to external collectors]]; \\
2. Get NAT Flow from Netstream third party systems (non DPI); \\
3. Form NAT Flow from FullFlow using QoE Stor/ 

===== Configuring receiving a separate NAT Flow with DPI or NETSTREAM =====

- Go to: Main Menu -> Administrator -> QoE Stor Server Configuration -> QoE Stor Server Configuration. \\

- Go to the "Receivers" section; add a new receiver; select "Receiver type" - NAT Flow; fill in the form for adding a receiver and click the "Apply" button; \\

- Go to the section of the form "NAT log settings" \\ - Enable populate IP-LOGIN binding from fullflow (FILL_IP_LOGIN_BINDING_FROM_FULLFLOW); \\ - Enable adding LOGIN to NAT log from binding IP-LOGIN (NAT_ADD_LOGIN_FROM_IP_LOGIN_BINDING). \\

===== Enabling import of NAT events from FullFlow =====

To enable import of events from FullFlow transmitted from DPI to QoE Stor: \\
 - Go to: Main Menu -> Administrator -> QoE Stor Server Configuration -> QoE Stor Server Configuration; \\

{{:dpi:dpi_components:dpiui:uгser_guide:qoe_analytics:natflow:way_to_receive:main_menu.png?700|}} \\


 - Import NAT events from fullflow (NAT_IMPORT_FROM_FULLFLOW) - Enable.

===== NAT Flow aggregation   =====
Go to: Main Menu -> Administrator -> QoE Stor Server Configuration -> QoE Stor Server Configuration; \\


{{:dpi:dpi_components:dpiui:uгser_guide:qoe_analytics:natflow:way_to_receive:main_menu.png?700|}} \\

Select "NAT log settings" -> Select fields to save during NAT log aggregation, Log filling time interval (15 minutes by default);  \\
