I have had similar issues with the MTU that were unrelated to pfSense. The trouble I had was will an ISP supplied DSL modem that could not handle the MTU sizes in a bridged mode. We had to replace the ISP router with a Cisco model that would work correctly. the problem router was a "SpeedStream". The problem manifested by certain sites not working and everything else appearing to work flawlessly.
