that or a bad cable.  polling making things worse makes sense with a
duplex mismatch, though also with a messed up cable.

when you end up with a mismatch, is it with two m0n0walls directly
connected with a crossover, or plugged into a PC or switch, or what?

You can force speed and duplex via hidden config.xml options, see the
FAQ.  DON'T do it unless you force BOTH SIDES.  Otherwise you're still
going to end up with a mismatch (and depending on how the devices
other than m0n0wall you're plugging into are configured, this is
usually how you end up with duplex mismatches in the first place).
