[Oisf-users] Suricata / only public trafic

[Amrith Z]

Hi,

Thx for your answer.

This is how I'm curently starting suricata :
/usr/local/bin/suricata --user suricata  -D --pidfile=/var/run/suricata.pid   -c /etc/suricata/suricata.yaml  -i eth1 'not src net 172.0.0.0/8'

Maybe my filter is not correct, because I still have entries where the source IP is my internal network.
Any idea ?

Thx.
