Debian strange port behavior.
I have a problem with a Debian7 openVZ server. The server runs a couple of VM’s, and I want to control it with Openvz-web-panel. However, I can’t use any services that open ports to the outer world. The main problem here is port 3000 that should work for OWP, but anything like Neorouter( port 32k) doesn’t work either. Netstat shows it as listening, but an Nmap scan shows a ridiculous amount of open ports, that are not shown as open in netstat:

Does anyone have a clue why this is happening? Thanks in advance 
PS: the error neorouter gave was: "Transport endpoint is not connected."

What I forgot to add: services like apache and openssh run fine. I even tried setting owp to port 21, since I don't use ftp, but that didn't work too.
When I have tried setup like this I had same problem, after some time I gave up and installed CentOS on host with openvz. Other way would be to use CLI for openvz since I assume everything else is working except OWP.
May this be an issue with fail2ban for some unimaginable reason? I see fail2ban in a list of socks.
