CentOS - Apr 2008 - iptables details

Hi all,
I'm a bit confused reading the RHEL System-Administrator-Guide regarding
this:
(1) iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to 
10.1.2.253:80
(2) iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j 
DNAT --to-destination 10.1.2.253:80

The first is for port forwarding, the second is said to be used for DMZ. But I 
tried both and the result is the same. Is there any difference between the 
two?

Thank you,

No. Maybe you misread?
