Setup routes for RFC 1918 ip space 

Setup general route for RFC 1918 space, as otherwise it will be sent to
the public gateway and not work. More specific routes that may be set
have preference over this generic routes.

When public network is RFC1918, we do not setup the routes to avoid
problems with internal-only deployments.
