Hi all, so im trying to set up a iptables firewall on a hwnode.
So i tried this script on the wiki pages
http://wiki.openvz.org/Setting_up_an_iptables_firewall

However, this script does not function properly?
Whenever i start the firewall all ports i set open etc are not open, and the script shuts out any connection from outside?

better put, the CT cannot resolve anymore ,whenever i turn the firewall on, nor can it ping outside ( beyond the hwnode)



Can anyone help me out with this one?

Please, carefully examine all iptables rules one by one on your system and find that causes the problem.

Iptables is empty before starting the firewall script

After the firewall is on, VZ CT are not allowed to connect/ ping / dns outside .

Of course, you have to look through iptables rules when firewall is on.
