I also tried to change the IP of the end machine to one in the 10.0.0.0 range, and the results were catastrophic.
Catastrophes are usually what teaches you the most. Or rather, understanding why it fails, and setting things straight. For example: you said catastrophic. In what sense? Assuming you changed the ip to 10.0.0.2 with a netmask of 255.255.255.0 and a routing table that looks something like 10.0.0.0/24 eth0 0.0.0.0/0 10.0.0.1 Could you still ping the middle machine? I'll bet you could. So I'm guessing that you forgot about the iptables rule you set up on the middle machine to allow routing, and that that rule had the source address 192.168.42.2 hard coded. Just a guess, mind you.
