Mirrored traffic flag doesn't work: traffic sent remains at 0.

Open endeavour opened this issue 8 months ago • 2 comments

Environment:

  • OS name: ntop/ntopng docker image running on opensuse tumbleweed
  • OS version: rolling
  • Architecture: x64
  • ntopng version/revision: v.6.2.250424

What happened: I am mirroring the port my router is connected to. In ntopng I set the interface connected to the monitor port to 'mirrored traffic' and add the mac address of the router. I expect ntopng to differentiate between ingress/egress traffic but sent packets remains at 0.

How did you reproduce it? As above

Hi @endeavour could you share your ntopng.conf file? Because probably you need to configure the local networs by using the -m option in order to properly work

I am running the docker image so I haven't modified the config file, but I am passing the following command line args: -i enp1s0 --local-networks="10.0.0.0/16"

You need to remove the :Mac address based traffic directions"
