Multiclient on OpenVPN for Windows

glaubersilva

Hi everyone!

That's my first post here, so be nice :-/

I have a VPN between two computers, one with Windows Server 2012 and other with Windows 7. It works perfectly, but now I need to connect one more Windows 7 on this VPN. I now this is possible using Linux as server, but on Windows Server when I create a new conf file e try to connect I receive this error message:

"tap-win32 adapters on this system are currently in use."

How can I create a new tap-win32 adapter on Windows ? Is this possible ?

Linux creates a new tun interface upon openvpn start,
in windows openvpn tries to open an existing TAP interface meaning that
you MUST have a available TAP device before starting openvpn,

Yes you can create as much tap interfaces you want if you use addtap.bat script...

Hi Michael. Thanks for your answer.

Can I create a VPN for multiple clients using OpenVPN for Windows? I mean, one single tunnel in the server and two workstations connecting.

yes you can,

you must use server directive & TLS based setup.
