Hello, i'm new here, and i'm sorry for my terrible English,
but i had read many topics, and there is a problem in my server configuration.
I've made all cert and key files and p12 file and import on android phone and it's connect easy without problem, but on Windows 7 there is error in log:

• Options error: On Windows, --ifconfig is required when --dev tun is used

I have no idea, what can I do to connect windows to VPN subnet.
In maunal there is info about server options that there is ifconfig in side that, but OpenVPN client for Windows write down that there is error.
Please help me. I need the OpenVPN connection.
