It's not a problem routing a private network to the internet via another
private network, but you do have to have your routes set up somewhere.
Simply connecting the interfaces and setting up the computer to route
between interfaces won't do it. If computers on the 172.17.0.0 network
point to 172.17.0.1 as their default gateway, then you'll need to add a
route to the 172.17.0.1 router that points traffic destined for the
172.18.0.0 network via 172.17.1.7. Computers on the 172.18.0.0 network
should use 172.18.0.1 as their gateway, and the box you're using for
your router should have a single default gateway, 172.17.0.1. If you
don't have access to the router, you could add the routes directly on
the computers for LAN-to-LAN, but you'll need the route on the router if
you want the 172.18 network to have Internet.
