When you say "router", I'm assuming you mean something like a Linksys
or D-Link cable or DSL router.  Those perform routing AND NAT.  You must
NAT, as the 192.168.0.0/16 network is not routable over the internet.

You must set the router between the internet and your 192.168.9.0/24
network to "port forward" the ports you want to the Linux box.  For
example, assuming the Linux box is at 192.168.9.5, you must have the 
router forward port 22 to that IP.  D-Link calls this service "virtual
servers", I'm not sure what Linksys calls them.
