How to make active MAC address invisible to router?

Is there any way possible to make a connected computers MAC address not visible on the active mac addresses of a router? I don't think there is, but I'm wondering if anyone here knows if that would be possible?
 
If the router can't see the MAC address, how does it know where to route? That connector is effectivly dead.

Routers DO hide MACs from the outside when DHCP/NAT is enabled.
 
The MAC address is never propagated beyond the router ("tunnels" & VPNs may be an exception) whether NAT is active or not.

The MAC is Layer Two, i.e., significant only to the broadcast domain that contains it.

As mentioned above, without a MAC, there is no way to know where to send the frames.

FWIW

As these guys say the HW is needed by the router..But you can find a nic that
the sys.admin can change.. there is a byte in there that will tell whoever looks that this is not a
globally unique HWaddress ,but one that was programmed in..
