Basically, it's NAT (network address translation). Source NAT aka
masquerading for outgoing connections, destination NAT aka port
forwarding for incoming connections.

That's port forwarding, yes. It must be set up on the box that does the
ICS. What OS does it run ?

You can indeed try to add a static route on the router with the subnet
behind the ICS box as destination and the ICS box address in the
router's subnet as gateway. But depending on the ICS implementation this
may or may not work (the ICS must be able to act as a regular router too).

Where's the Linux in this setup ?
