   If it is ethernet (you never mentioned that) then it needs a MAC   
   address, otherwise sometimes known as an ethernet address.   
      
   Normally they are globally unique 48 bit numbers, usually   
   stored in ROM on the host.  If you clone the host, you must   
   change the MAC address.  For IP to work, it really only needs   
   to be unique on the subnet, but that is exactly the problem   
   you have.   
      
   If the whole thing is on one FPGA (just a guess) then you somehow   
   have to get a new MAC address in there.   
      
   Post the output of the arp -a command on the PC.   
   The output if netstat -r would also help.
