  • If I understand your problem, you are concerned about some packets being blocked and you don't understand why?  Those packets appear to be out-of-state, and are normal for pfSense.  When a connection is closed by one side, the other side will send an ACK packet to say that it received the close request.  Since pfSense has already closed the connection, it will drop the packet that acknowledges the connection close request.  Since pfSense already considers the state closed, it will reject that ACK packet and log it.



  • Understand, because doing this with almost all packages of VPN, which traffics Squid and Voip and thus falling connection or getting dumb Voip

    Is there any way to fix this?



  • If it is out-of-state packets, then you should just ignore them.  Are you having some kind of problem that these dropped packets are related to?



  • Yes I am, is losing direct connection Voip and Terminal Server, giving drop in constant 3389 5060 3128



  • I think your problems are not related to these packets.  TCP:FA is a FIN ACK, which is acknowledgement of receiving a TCP teardown request.  This packet is the most commonly blocked out-of-state packet.

    Now, on to your actual problems.  I'm not sure if I fully understand you, but I am guessing that you have these two sites connected by OpenVPN, and you say that there is disconnection between the sites?  When a disconnection happens, check Status - System Logs - System - General and Gateways.



  • Oowoo

    I guess it's a problem

  • The problem you are seeing may be related to apinger.  Search these forums and you will see a LOT of apinger problems with 2.1.x.  This functionality has been improved in pfSense 2.2.  You might want to look at upgrading.
