We have several virtual machines which are connected in a private virtual network connection.
Internet access for these machines is provided via dedicated virtual machine which has apache proxy server on it (they all use this machine as proxy).
The problem now is that from several machines we need to connect to external VPN Server, but it seems that VPN connections don't work over apache proxy.
Any suggestions on how to enable VPN connection over apache proxy (or some other proxy)?
Some other solution?
