Now in theory I think this should work in my environ at home?

I am on DSL and have an internal IP address such as 192.168.1.1 and a specific internal gateway address....now, if I add this AnalogX to my machine, can I realistically create more 192.168.1.x addresses for my other machine and have those machines utilize static internal IP address as the gateway itself? Is that correct? Any insight helpful. Thanks.
