Proxmox 3 CT ports problem

[harpnet]

Hello!
Yesterday my CT with WHM suddenly failed. Now Dns port 53 is blocked, i disabled all iptables rules but isn't working.
I can acces CT via local network, and ping other external sites inside of CT. Can u help me how to resolve this problem?

Hi,
"suddenly failed" has normaly an good reason.

Any helpfull output in the logfiles?

But with your insignificant info, it's very very hard to give an hint, how to "resolve this problem".

Do your homework - which network modell/IPs do you use? Why is port 53 blocked? (in use?). What do you see with tcpdump?

Hi Udo,
Problem solved.
I rebuilded network configuration on host and disabled iptables, then i added ip from putty with command : vzctl set xxx(container number) --ipadd xxxxxxx(ip add) --save

I think , the problem is from iptables because i have an old-old-old version and i dont know how to upgrade. I will try to install again
