Static MAC address

[nobaq]

Hi,

To have a special configuration pushed to my clients, I want to give each client a static MAC address.

I found lladdr. However, this option seem sto be ignored! I set e.g.:
dev tap
lladdr 00:FF:33:AC:7F:84
dev-node "OpenVPN"

but ipconfig /all still reports the old MAC address - also the DHCP server on the other end receives the old MAC. Is lladdr broken?

Is there a different way how I can set a static/persistent MAC address for a tap device?
Thank you!

can you post the output of ipconfig on your windows client?

if you ommit dev-node parameter,still not working?

Hi, thanks.

No change if I remove dev-node.

But when starting the tunnel from command line I found an interesting message now: "Thu Aug 08 22:41:03 2013 Sorry, but I don't know how to configure link layer addresses on this operating system."
