      Today I am seeing a steady 3 Mbps of traffic from my LAN and my DMZ going into pfSense and going nowhere.  When I adjust the graph settings to see what's happening, it tells me that this traffic is coming from 255.255.255.255.

      What is this phantom traffic???

        Try viewing some traffic "tcpdump -eni <nic>" on a ssh/console perhaps write it to file with a extra parameter "-w /tmp/ghosttraffic.pcap" for loading in wireshark and further analysis.?.</nic>

          Heh, I was hoping to get a hint without having to break out Wireshark.  But having done it, that traffic seems to be DHCP-related.  There is a ton of discovery, requests, offers and NAKs that never end.
