Subject: Manipulating UDP sender's address

Is there a way, in general, to "fake" a sender's IP address when sending 
a UDP packet? I need to receive a UDP packet on one port and redirect it 
to another "pretending" that it is from the original sender.

Even if it is not possible from Ruby now, I would appreciate any 
pointers so that I can make an extension to do it (if at all possible).

Gennady.
