Uhm, how are you expecting that the target machine will react to these 
forged TCP packets?

Reagarding the MAC addresses, the hardware does not modify them, so you need 
to fix them as well.

Have a nice day

In a previous email I was directed how to refelct tcp packets to a third 
party. Specifically now, I have to read a dump file that was prepared by 
Ethereal and inject every packet to a third party. The source and the 
destination of the dump file packets are different from those of the 
injected packets so I beleive I have to modify in every packet, the IP,TCP 
and CRC check. The data itself should be used as is.
Do I have to refer to other fields like the ethernet address or this is 
modified automatically by the hardware?
IS there anything else that should be modified?
