Does that mean that the snyc-LED on your DSl-modem goes off, and that it 
resyncs again (usually a flashing sync-LED during that procedure or 
something like this)? If that's the case (meaning that your DSL-modem is 
really loosing it's sync) it's nothing between the modem and your m0n0wall.
Losing the DSL sync usually is because of a faulty splitter, a bad line 
or problems in the station your phoneline ends in. And if so, it's a 
problem of your ISP, or whoever is responsible for the phone line.

If you can, try another DSL-modem (different brand and such), there's a 
(small) chance that this will solve your problem.
