Hi Simone, Here the ntopng and nNrobe configuration used.
Ntopng: --interface eth0 --interface tcp://127.0.0.1:5556 --local-networks 172.22.9.0/24,192.168.0.0/16,172.22.0.0/16,10.0.0.0/8 --daemon --user ntopng --pid /var/run/ntopng/ntopng.pid --http-port 0 --https-port :3001 --data-dir /var/lib/nst/ntopng --dns-mode 1 --disable-autologout --disable-login 0 --sticky-hosts none --http-prefix /ntopng --ndpi-protocols /etc/ntopng/protos.txt nProbe: /usr/local/bin/nprobe -i none -n none --zmq tcp://*:5556 -b 2 -3 6343 --online-license-check --as-list=/usr/share/ntopng/httpdocs/geoip/GeoIPASNum.dat --city-list=/usr/share/ntopng/httpdocs/geoip/GeoLiteCity.dat -G --pid-file /var/run/nprobe/nprobe.pid -V 9 --disable-cache --zmq-disable-buffering I don't know if I can attach pictures to this message to explain what I mean by saying that my collector ntopng return sflow to the remote Meraki device. Traffic from my collector IP is almost 100% sent and when I check the Protocol detail, it show that it's sFlow (Sent 100%) to my remote Meraki device under the Peers tab!
