I am a Linux expert, fortunately. First, is this what you really want to do? Why only ports 3000-3500? Do you really want to do port forwarding? That is, when a particular port comes in on the in-between machine it is just forwarded to a particular port on the other? Second, if you poke around, a solution for your particular case probably exists. For instance, FTP has some pretty funky behavior as far as port are concerned, but there is a Linux kernel module that will make iptables do the right thing.
