Why network packets are dropped

I'm trying to get traffic between two pfsense interfaces on a third interface using the 'Bridge' option of pfsense (SPAN). For instance I want to see traffic between LAN and WAN through DMZ VM. This works very well on VMWARE, but on OpenStack, I only view broadcast network packets.

I did a tcpdump -i DMZinterface on pfsense, the traffic is present, but not on DMZ VM.

[LAN] 192.168.1.2---------192.168.1.1 PFSENSE 192.168.2.1----------- [DMZ] 192.168.2.2 | WAN

I do not know if OpenStack is blocking these network packets.

I have already disabled the port-security-groups for routing packets on pfsense.

Thank You
