You can see in your computer what static routes are defined putting in CMD “route print”.
You must compare this conected with OpenVPN and not conected to see what is the diference.
When you are conected by OpenVPN, OpenVPN client put one line for routing to OpenVPN Server (if you mark one in Advanced Options --> Client has access to these networks on IPFire’s site).
With the same openvpn client from android I can access the green network and I can not go out to internet …
but from my windows 10 I cant access green network neither internet
