The cFOS program procedure for diagnosing the network, as well as other network tools, may affect the correct routing. One possible solution is to deactivate all network services and protocols afferent to the CyberGhost VPN network connection. Proceed as follows:
- Use the right mouse button to select 'CyberGhost VPN Netzwerkverbindung' ('CyberGhost VPN network connection') in your Windows network connection administration interface.
- Select 'options'.
- Un-check all boxes, except for 'Internet protocol (TCP/IP)', respectively, in Windows Vista 'Internet protocol version 4 (TCP/IPv4)'.
It is very possible that you will encounter this problem again, because certain programs, amongst which cFOS, are automatically reactivated after a certain period of time for the network board. If so, we recommend that you deinstall the program, especially because, when using CyberGhost VPN, cFOS is rather an obstacle than a help.
Note from the cFOS FAQ:
"[...] cFosSpeed supports VPN. To be able to use traffic shaping via VPN connections, you need to set the value 'ping_dest' to '10.128.0.1' in the [param] section of the cFosSpeed.ini file. (Note from administrators: 10.128.0.1 is an IP address from the CyberGhost VPN network).
By also adding the parameter keep_bindings=1 to the [param] section of the cfosspeed.ini file, you can deactivate unbind operations for network adapters that do not seem to be used. Use this when VPN connections are terminated.Source: cFOS FAQ
