What network cards are you using?

The physical interface is a Realtek PCIe GBE network Controller (onboard ethernet controller).
This Pfsense is running over Vmware player over this interface. WAN and LAN pfsense interfaces are vlans. These are transported over vmware bridged virtual interfaces directly connected to the physical interface.

That might be the cause of your problems.

Otherwise, I have no idea. :(
