     +If a subscriber has [[en:dpi:opt_cgnat|the NAT 1:1 service]] activated, then the ''VasExperts-NAT-IP'' attribute (VSA vendorId=43823, attrId=21) containing the subscriber's white address will be added to the Accounting-Request. The''Framed-IP-Address'' attribute holds the gray address of the subscriber.
     +
     +Starting from the VAS Experts DPI version 8.1 it is possible to pass the white IP address within the ''Framed-IP-Address'' if the subscriber has the NAT 1:1 service activated. For this purpose you should specify the ''acct_framed_ip_address_nat'' fastpcrf.conf option. 
     +
     +By default ''acct_framed_ip_address_nat=0'' and the attributes have the following values:
     +  * ''Framed-IP-Address'' - gray subscriber address.
     +  * ''Calling-Station-Id'' - subscriber MAC address, if it is known (subscriber MAC addresses are known only in L2 BRAS mode). If the MAC address is unknown, this attribute is not used.
     +  * ''VasExperts-NAT-IP'' - white subscriber address, if the subscriber has the NAT 1:1 service activated. If NAT 1:1 is not activated, this attribute is not present.
     +
     +If the ''acct_framed_ip_address_nat=1'' and subscriber has the NAT 1:1 service activated, then Accounting-Request will contain attributes with the following values:
     +  * ''Framed-IP-Address'' - white subscriber address behind NAT 1: 1
     +  * ''Calling-Station-Id'' - gray subscriber address
     +  * ''VasExperts-NAT-IP'' - white subscriber address
     +
     +If subscriber hasn't the NAT 1:1 service activated, then the attributes will have values as if ''acct_framed_ip_address_nat = 0'' was specified.
