I assume that you use ADSL from a german ISP like T-Com, Arcor or the like.
If so, please have a look at the status.php site on your m0n0wall. Look 
for the MTU value bound to the ethernet interface your DSL modem is 
attached to. You find the information in the second box called "Interfaces".
If that MTU is 1500 that could cause problems (although it should be 
1492 for PPPoE connection). Some ISPs like AOL need a MTU of 1400 for 
DSL via PPPoE.
