I am trying to host a freind on my VPS and he is in Iceland and has a .IS domain, this requires UDP and TCP ports 53 be opened. I have opened these in APF and even tried to drop the firewall totally but it is still blocked.

I checked in the control panel and it is not blocked there so I am not sure why I am having an issue with this. When on a dedicated server we were able to open these ports without an issues but now ISNIC is saying they are not opened and won't let us register the nameservers with them.

Any help would be greatly appreciated as I am very new to Virtuozzo and VPS in general.

Here is something else I tried, The port 53 issue is only for ns2 as ns1 seems to work so the main issue is that ns2 will not open these ports correctly regardless of if I add them to IPtables or not to allow.

Here is what I used to attempt to open the port

iptables -A INPUT -p tcp --dport 53 111.222.333.444 -j ACCEPT

The IP address is the IP of ns2

You probably have to submit a trouble ticket with EV1 and request that they open up the port on the server (as well as you leaving it open on a firewall you are running). AFAIK, they only allow certain port ranges open, and this may be a port not yet opened on the server you are on.

On VPS, you only have a virtual lan card which your firewall controls. Their firewall controls the actual lan card and affects all users.

That is actually not true. Each VE runs its own iptables. Settings for the hardware node do not apply to the virtual node.

There are some problems with APF under Virtuozzo though, you might want to check with EV1 if the hardware node is prepared for APF. The procedure is explained on SWsoft's website (FAQ - search for APF).
