If it's private it doesn't really matter: these networks were defined to 
NOT be on the public internet that's all,

Many routers will allow multiple local networks to be defined and will 
route between them.

If not the simple answer is to insert a linux machine preferably with 
two interfaces, but linux allows two IP addresses to be assigned to a 
single interface

There is something fascinating about science. One gets such wholesale
