Think about the replies. 192.168.0.3 sends a packet to xxx.dyndns.org, that gets translated by 192.168.0.1 into 192.168.0.2 192.168.0.2 receives the packet, sees that the sender is 192.168.0.3, and replies. Therefore 192.168.0.3 sent a packet to xxx.dyndns.org and got a reply from 192.168.0.2. It can't handle this, so fails. (I'm assuming in all the above that xxx.dyndns.org does not resolve to 192.168.0.2, of course).
