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.
