Something wiped my MAC address!

I had an old PC chips M810L mobo lying around, so built a little system
based on it for my daughter.

When setting up my router/firewall (Dlink DI-604) to share broadband for the
(now 3) PCs we have, I was setting up static DHCP for each, and the DI-604
reported the M810's MAC addy as 00-00-00-00-00-00!

The DI-604 works fine assigning an IP to that MAC... I'm well aware that all
MACs *should* be unique, but does it really matter when sat behind a
router/firewall?

Cheers,

Andy

What does the system itself report it as?

For TCP/IP (I don't know about anything else), MACs never escape the subnet,
ie they go no further than the nearest router. MACs within a subnet must be
unique.

Xp pro agrees it's all zeros...

Thought so. I'll leave it as is then..
