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

There are three ways to generate a NAT log in QoE Stor (statistics server):\\ 
  - Receive the NAT Flow as a separate stream from the SSG. To do this, configure [[dpi:opt_cgnat:log#export_of_translations_to_external_collectors_in_ipfix_format|export of translations to external collectors]] on the SSG device; \\
  - Receive NAT Flow from Netstream of third-party systems (not from SSG); \\
  - Generate NAT Flow from FullFlow using QoE Stor. 

===== Configuring reception of a separate NAT Flow stream from DPI or Netstream =====

  - Go to: Administrator → QoE Stor Configuration;\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:main_menu.png?250|}}
  - Go to the "Receivers" section; add a new receiver; select "Receiver type" — NAT Flow; fill in the receiver form and click "Apply";\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:receiver.png?1000|}}
  - Go to the "NAT Log Settings" form section:
    - Enable IP-LOGIN binding from fullflow (FILL_IP_LOGIN_BINDING_FROM_FULLFLOW);
    - Enable adding LOGIN to NAT log from IP-LOGIN binding (NAT_ADD_LOGIN_FROM_IP_LOGIN_BINDING).\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:netstream_ip.png?1000|}}

===== Enabling NAT event import from FullFlow =====

To enable importing NAT events from FullFlow transmitted from DPI to QoE Stor:
  - Go to: Administrator → QoE Stor Configuration;\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:main_menu.png?250|}}
  - Enable NAT event import from fullflow (NAT_IMPORT_FROM_FULLFLOW).\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:right_enable.png?1000|}}

===== NAT Flow aggregation =====
  - Go to: Administrator → QoE Stor Configuration;\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:main_menu.png?250|}}
  - Select "NAT Log Settings" → choose fields to save when aggregating the NAT log and set the log fill time interval (default: 15 minutes);\\ {{:dpi:qoe_analytics:implementation_administration:configuration_setup:nat_flow:true_agregation.png?1000|}}
  - Save the changes and restart the service.
