Thanks for the reply,

The SuSE kernel is only 2.4.4, I'm sure I've read somewhere that they 
have applied the patches. But I will compile a knew kernel with the 
patches myself and see what happens.

I did search but I was sure that the 
linux-2.4.4-openssl-0.9.6a-mppe.patch.gz was applied :):) Plus Win2K 
defiantly was using MPPE 128.
