Pretty much the same config as myself, with the exeption that I have:
set bundle enable compression
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set ccp yes mpp-stateless
I've set the MTU to 1460 - as you have, which seems to give me 1396
when a client connects.
So far, I've only tested this with Windows XP machines, so I'm not sure
if anything OS-specific concerning the MTU is negotiated during the
connect phase, or even if having MPPE enabled would affect it.
I imagine you've tried setting the MTU to other values?
Best regards,
-Andy
