I believe what you're talking about is called "port-forwarding".
Normally, that's a function of the routing/firewalling code on the box,
but if it's gotta be the same on all platforms, I'm sure you can write a
simple Java app that binds to a port like any other server and just
forwards the data.
Note that there will likely be restrictions on what port a Java app is
allowed to bind to.
Me, I'd just set it up with IPTables, but that's Linux-only.
