They can.

Please be aware that both interfaces use the same MAC address. This
is ok as long as you don;t try to connect bioth to the same subnet.

Well, it makes little sense to guess how you ifconfig'ed the
interfaces, please provide more information.
My bet is that you tired to run both ethernet ports in the same
network, and that you're experiencing a conflict caused by two
identical MAC addresses.
