Your computer is in your LAN, same as 192.168.1.1. So if your computer sends a packet to 192.168.1.1, the packet goes directly to the destination machine, without passing pfSense. Only packets for IP addresses outside your LAN subnet are sent to the default gateway (pfSense).
So pfSense is not able to route these packets to anywhere, cause it doesn't get them at all.
