L2TP VPN service is installed, your L2TP VPN username is

Thank you very much for your help!

 

Hi there, is your firewall UP? In most cases CentOS comes with the firewall enabled so you should add a rule to open the VPN port or just disable the firewall and test the connection to the vpn server

 

Could you please teach me how to open the ports via Putty? What do I write on Putty and which ports?

I am horrible at these things.

Thanks again!

 

Usually the VPN ports are 443 and 1194:

1. iptables -I INPUT -p tcp -m tcp --dport 443 -j ACCEPT
2. iptables -I INPUT -p tcp -m tcp --dport 1194 -j ACCEPT
3. service iptables save

 

Have you checked iptables compatibility ? Also its not possible to run VPN onto OpenVZ
You should have KVM or Xen to get VPN work perfectly with all functions and features.
