Can I send packets on the same computer running tcpreplay?

Generally speaking no. When tcpreplay sends packets, it injects them between the TCP/IP stack of the system and the device driver of the network card. The result is the TCP/IP stack system running tcpreplay never sees the packets. One suggestion that has been made is using something like VMWare, Parallels or Xen. Running tcpreplay in the virtual machine (guest) would allow packets to be seen by the host operating system.
