There is nothing that says a gateway has to be in the same network, even a
totally different private IP could be used as gw (as is commonly done for
ppp or pppoe), by using a host route to the gateway (if the gateway device
is capable of that).
However, when using hardware broadband routers, your options are often
limited to a specified subnet. So if your method gets the job done, that
is all that matters.
