      Hi,

      I've been seeing a lot of this message in my system log, lately. What does it mean and is it something to worry about or I can just ignore it? My pfSense [2.0.2-RELEASE (i386)] seems to be working without any problems or performance issues, aside from that message.

      Thanks for your help.

        That means that it received an ARP packet from some other device on the network and that device sent a packet that wasn't recognized.

        It could be coming from the WAN or LAN, hard to tell without running packet captures and looking for it.
