[Openvpn-users] Duplicate MAC addresses with OSX clients

[Andrew Boyce-Lewis <aboyce@xxxxxxxxxxxxxx>]

I am running a bridging network and have discovered that the OSX tun/tap driver apparently hard codes the MAC address of the tap interface (so all OSX clients have the same address). ( Tiger version http://www-user.rhrk.uni-kl.de/~nissler/tuntap/ )

Has anyone else run into this problem? or can anyone suggest any possible workarounds? I've read that the windows and linux tap drivers use an algorithm to generate a non-sense MAC address and assign that to the interface... I suppose that might need to be implemented for the OSX version. 

 Thanks,
