    I have a J-flow issue where we are not getting  the CGNAted  down stream flow data.  This on MX480 with MPC serivce card.   I tried with and without customer facing  sampling. this  config was working on MX104  with the MIC card. When I moved it to MX480. all plublic subnets work but the CGNated.  

    this is the configration :

    set chassis fpc 0 sampling-instance inline-JFLOW-1

    set chassis fpc 0 inline-services flow-table-size ipv4-flow-table-size 15

    set services flow-monitoring version-ipfix template ipv4 flow-active-timeout 60

    set services flow-monitoring version-ipfix template ipv4 flow-inactive-timeout 15

    set services flow-monitoring version-ipfix template ipv4 template-refresh-rate seconds 30

    set services flow-monitoring version-ipfix template ipv4 option-refresh-rate seconds 30

    set services flow-monitoring version-ipfix template ipv4 ipv4-template

    set services flow-monitoring version-ipfix template ipv6 flow-active-timeout 60

    set services flow-monitoring version-ipfix template ipv6 flow-inactive-timeout 15

    set services flow-monitoring version-ipfix template ipv6 template-refresh-rate seconds 60

    set services flow-monitoring version-ipfix template ipv6 ipv6-template
