As IP address, in linux is possible to change the MAC Address as follow:

• turn down the interface (ex. eth1):

# ifconfig eth1 down

• then set the new mac Address

# ifconfig eth1 hw ether 00:11:22:33:44:55

• verify the new address:

# ifconfig eth1

eth1      Link encap:Ethernet  HWaddr 00:11:22:33:44:55
             BROADCAST MULTICAST  MTU:1500  Metric:1
             RX packets:0 errors:0 dropped:0 overruns:0 frame:0
             TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
             collisions:0 txqueuelen:1000
             RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
             Interrupt:41 Base address:0xb000

•  now set again your interface: ip and routing table.
