Ah, I forgot to mention, machine 2 is on a private network that is not routed in any way. So, there is no default gateway for machine 2... That's why I was thinking the source port would have to be re-written internally such that machine 2 would know to send it back through machine 1 and then on to the internet... ?
Then indeed you need to SNAT the forwarded connection. Also make sure that machine 1 has IP forwarding enabled.
