I know IP address aliasing is possible, but is MAC Address aliasing possible, too ? I want to have multiple IP addresses configured via DHCP because my ISP doesn't allow anything else, so I am trying to do the following: Code: auto eth0 iface eth0 inet dhcp hwaddress ether XX:XX:XX:XX:XX:XX auto eth0:1 iface eth0 inet dhcp hwaddress ether YY:YY:YY:YY:YY Problem is that if I set the HWADDRESS of eth0:1 to Y, the HWADDRESS of eth0 also changes to Y. Does anyone know a workaround ?
