Hello Rodrigo,

> The scenario is: I have 3 machines and I want to create a tunneled connection among them but using a private network. Those virtual machines are from different vendors. I can connect them, but I don't know how to add this virtual network. Any ideas or suggestions?
> Example:
> | 213.XXX.XXX.XXX | === | 5.XXX.XXX.XXX | === | 88.XXX.XXX.XXX | -> Real IP
>         sun                  moon                    earth
>      -> Virtual IP

Add those virtual IPs with scope global to a dummy interface on the respective virtual machine (or on loopback, if your Distro supports configuring tha).
Then just set left- and rightsubnet accordingly and configure site-to-site tunnels with your virtual IPs.


Mit freundlichen Grüßen/Kind Regards,
