Hi, VPP configuration look good to me, I am not sure what is wrong. Maybe try to check “show interface” output, IPfix should add 9 additional tx packets for GigabitEthernet3/0/0 after ping and “ipfix flush” command.

I would like to check my topology and configuration with you. thanks in advance. Client1 IP: 2.2.2.2 Client2 IP: 3.3.3.3 DUT config: GigabitEthernet3/0/0 (up): L3 2.2.2.1/24 GigabitEthernetb/0/0 (up): L3 3.3.3.1/24 vppctl set interface nat44 in GigabitEthernet3/0/0 out GigabitEthernetb/0/0 vppctl nat44 add address 40.40.40.40 - 40.40.40.254 vppctl set ipfix exporter collector 2.2.2.2 port 4739 src 2.2.2.1 vppctl nat ipfix logging Client1: nfcapd -l /root/log/ -E -p 4739 client1 ping client2 successfully. the src addr of echo packets in DUT is changed to 40.40.4 0.254 and also in return path, the destination of reply packets is changed to original address again. I mean we have the correct nat functionality. but about ipfix, the collector doesn't receive any log. I checked it by tcpdump and nfcapd. Best Regards,
