Hi,

I followed the tutorial:
http://wiki.openvz.org/Setting_up_an_iptables_firewall#Setti ng_up_a_HN-based_firewall

But Now I want to enable NAT (CT to be with Private IP)

As described here:
http://wiki.openvz.org/NAT

iptables -t nat -A POSTROUTING -s 192.168.12.0/24 -o eth0 -j SNAT --to xx.xx.xx.xx
iptables -t nat -A PREROUTING -p tcp -d xx.xx.xx.xx --dport 888 -i eth0 -j DNAT --to-destination 192.168.12.12:80

But nothing happens?

No error, but when I issue iptables -L -n noting appears?!

Host is CentOS 5

It should be obvious mistake, but cannot figure it...

Any suggestions?

If additional information is needed, please let me know.

Sorry for the delay... was a bit busy

Yes that command shows the existence, but the command does not work.

I've decided to switch to shorewall since I've used it in the past + I need more advanced firewall that the one in the firewall script and it worked.
