Nope, this will not work.
Since you are using private {non-routable} Ip addresses on your internal
network, you have to do IP Masquerading on your outbound interface.
If you've never done this before it can be somewhat interesting to setup -
wiser heads than mine can help with that.

Nope - once you get Masquerading setup, you set your old_box as the
gateway {route add default 172.16.4.1} and just let the other box handle
it. The masquerading script should handle all changes required.
