Hi All,
I'm a newbie to this list and I apologize if this question has already 
appeared in previous posts.
I would like to do NAT from a private range to a public range of the 
same size, in a way that just
the network part of the IP address would be translated.
For example, I would like a single iptables rule to map 192.168.10.0/24 
=> 10.1.1.0/24 as follows:
192.168.10.1 => 10.1.1.1
192.168.10.2 => 10.1.1.2
.
.
.
192.168.10.254 => 10.1.1.254

I know that I can do it by defining the whole set of rules explicitly, 
but I'm looking for a better solution in terms of simplicity and 
performance.
Can anyone help?
Thanks,
