could it be you have two machines accidentally set up with the same IP - perhaps broken DHCP? = I very much doubt this is the case. Some are static, rest pfSense is doing the DHCP. All devices on the LAN are functioning as expected.
if you've got managed switches, can you check their arp tables to see where those mac addresses live? = unmanaged switches. I have checked all the MAC addresses I can find on the LAN and local WAN, (pfSense makes this easy with the ARP and DHCP lease pages) put into spreadsheet and searched the errant ones for, none are found. I suppose one could find the ARP range assigned to what manufacturer, but that sounds hard and non specific. are you using vlans, and if so could you have accidentally joined them? = Not sure, have got PPTP setup, but most of time it is unused. Problem occurs when PPTP not operational. Does that answer? It was only implied, to be clear em0 is WAN, em1 is LAN. I know others on the same cable network who are having similar problems.
