Hi Enrico,
i see, i saw via tcpdump you get also the dhcp traffic.
if the packetfence is listening on the interface :
netstat -anu | grep :67
and similar output comes out:
udp 0 0 10.25.0.1:67 0.0.0.0:* LISTEN
then you might be facing a bug. sorry i cant think of something else
and cant help further. hope someone in the community comes up with a
solution.
Best Regards
Farbod

Hi Farbod,
no because my network profile is enforcement and PF server and DHCP
Server
are on the same vlan.
/[INFN-WIRED]
filter_match_style=all
sources=RADIUS-AAI
locale=
advanced_filter=
autoregister=enabled
filter=connection_type:Ethernet-EAP
scans=OpenVAS-WIRED
/
So PF would see all dhcp sessions. Is it true ?
