Iptables and multiple ip ranges

[Ignacio Bernal <soporte-sist () unav es>]

I'm trying to configure a linux firewall using iptables, to use non uniform
ip ranges like :

192.168.0.27-192.168.0.63

... that could not be defined using the ip/mask syntax. I wonder to know if
that can be done, and how.

Thanks.
