I'm not sure what you mean by "support UDP".  Tcpreplay doesn't know
anything about layer 2-7.  It merely reads the (ethernet) frame and
writes it out the approprate network interface.  If you're expecting
it to maintain state or anything like that, you'll be sorely
disappointed.

tcprewrite on the other hand does understand layers 2-4 and can modify
packets accordingly.
