Firewall prevents connection on Internet

[Guest flintsec]

Sorry for my English. Problema is: I have allocated local network. I connect to the Internet through KVpnc. When I connect to the Internet, appearing message "Network out on the interface eth0".

I trying to disable the firewall to remove checkbox eth0 and ppp0. But checkboxes not removed. I use Mandriva Power Pack 2008.0. How can I remove the checkboxes and go on the Internet.

Try going to Configure Your Computer > Security, and set the security level to Standard. Next go to set up firewall and uncheck all the boxes on the first page. Close the pages. Can you connect now?

I set the level of security "Standard" and even "Low". Check "Allow access to all services through the Internet". Reloads. And then again says "Network out on the interface eth0".

In the Internet I get through the computer neighbour.
