[pptp-server] IPX howto

[tmk]

i'm working on it, but my old 486 linux box is giving me trouble so i'm
setting up another this weekend and things should be better then.

If you all don't mind, i'll be doing the howto on the 2.2.x series kernels
only. Should be pretty similar for 2.0.x but you never know (last i
checked ipxripd was written fo the 1.x series of kernels, and i gues IPX
hasn't changed too much since then :)
