I'm suspecting the mark of "0x1/0xffffffff" originally in the tutorial was
a typo.
Does it work any better when you change that to "0x1/0x1" ?

Sorry for my last resending email. Actually I didn't have Amos reply in my inbox but I could find it on the Mailing List archive. Anyway here is my /etc/sysconfig/iptabels :

As you can see there is no 0x1/0xfffffff there ! it is just 0x1 but the iptables itself show it as what I paste in my last email itself. Any idea ?
