[En-Nut-Discussion] ip filtering

[José Hugo Pérez Casanova]

The IP filtering in Linux is very interesting. It is based in 3 basic 
chains, one for input, one for forward and one for output (others may be 
added).

I think it will take much space to implement it. Maybe a simple solution 
like the one provided by the tcp-wrappers should be very simple to 
implement. It is based in a couple of files: hosts.allow and hosts.deny.
