No.  With the end points set to an MTU lower than the m0n0wall devices, you 
remove them from the equation.

I always do the direct registry entry, so I do not know.

MTU is "supposed" to be negotiated.  And we know how well Microsoft follows 
the standard.  It "should" work just set on the server.  You may have to set 
every device in practice.  I have had to do this for many systems that could 
not brows some websites like microsoft.com and it was MTU.  Gotta love it!
