NATing a range of IPs

[Matthew Kopishke <matt@kopishke.org>]

Hello folks,

Is it possible to NAT a range of IPs?  Like for example:

iptables -t nat -A PREROUTING -p tcp -s <range of IPs>  --dport 80 -j 
REDIRECT --to-port 13001

As you can see what I would like to do is redirect port 80 from the 
range of IPs (in this case 65.18.71.1 - 65.18.71.240) to port 13001.  
It works great is I try one IP, or the whole block, I'm just unsure of 
how you represent a range?  I see references to a IP range in the man 
pages, but no examples.

Thanks,

Matt
