Fair enough. Next issue then: as far as I know, broadcast packets are by default not routed across subnets by gateways. Which is a good thing. That would explain why your receiver doesn't see the packets unless its interface IP address is in the same subnet as the sender's. However it doesn't explain (for me) why the tcpdump program running on that same receiver machine still happily spits out received packets. Unless the routing between the subnets is somehow done on the receiving machine itself? My knowledge of networks and TCP/IP ends here I'm afraid.
