on Windows: no, Windows simply won't let you do that without a reboot

On Linux/MacOS: this is possible (and useful) only in 'tap' mode. Read The Fine Manual and look for

i have only windows.. so there is no chance to change/spoof the MAC address of VPN on windows...

it's possible but not without a reboot - simply edit the MAC address of the TAP-Win32 adapter in the registry, reboot , and presto.

that's off-topic for this forum, really. Search the web for setting the MAC address on a windows network adapter, that should apply to the tap-win32 adapter as well.

It should be something like: go to the network adapters screen, select the 'tap-win32' adapter, click 'configure' . Go to the "Tap-win32 Adapter v9 Properties" page, tab "Advanced" and change the entry "MAC Address"

Sorry to necropost, but I have been wondering this myself.

Due to installing OpenVPN *before* cloning an image, I have 14 machines on the network with the same (randomly created TAP-adapter) MAC address.

It _probably_ isn't hurting anything, since they all get differently-assigned IP addresses from the OpenVPN server and most of the communications is TCP/IP and Windows file sharing...

Is the registry method: http://www.windowsreference.com/networking/how-to-change-mac-address-in-windows-registry/
still working in this case? It should also be an interesting test to see if it works with Windows 7 x64.

Thoughts?
