Hi,

My Pfsense firewall has 3 interfaces, WAN, LAN and DMZ. Mac OS computers in my LAN net can not connect to an external site on net. When I sniff the traffic on both WAN and LAN interfaces I saw a situation like this:

MAC -> LAN -> WAN -> SITE (SYN)
SITE -> WAN x LAN x MAC (SYN ACK)

I see SYN ACK packages on my WAN interface coming from SITE but I don't see them on my LAN interface. Packages getting lost between my WAN and LAN interfaces. Is there any way to debug the problem? / Is there any one having the same problem?

Thanks.
