Setting a static MAC address

Hello.

I am using Parallels 5.0.9344 on a MacPro running OS X 10.6.3. I am using both en0 and en1 Ethernet connections on the Mac. en0 is reserved for my Mac. I use en1 (which is Built-in Ethernet 2) for Parallels.

I want to allow my router to assign the same IP to Parallels each time I start it up. I can do the static IP assignment based on MAC address using my router (it has so-called static DHCP capability). Problem is, I can't seem to set a static MAC address in Parallels.

I have selected Bridged Networking -> Built-in Ethernet 2 within the Parallels VM config, but I can't change the MAC address. Does anyone know if what I am trying to do is possible?

Thanks.
Stu
