Since the DF bit is set and PMTUD is being disobeyed, I discovered that MSS is obeyed. Therefore, I resolved my problems by doing the overhead math and setting the MSS adjust parameter on the LAN facing interfaces of my routers. This workaround is definitely more scalable than changing the system MTU on all my machines.
