Does iptables dnat change the originating IP address? Is it supposed to?

Packet from 1.1.1.1 hits iptables destined to 10.10.10.10. That external
address is dnat'ed to 192.168.0.10 and then the packet is sent to the
the final address.

I have a system that seems to be changing the source IP of dnat packets
so that all connections appear to come from the iptables machine and not
the outside.
