Concentrating Communication
Some large customers will connect the service boxes through an additional local
router, so that it need not have a direct Internet connection and to minimize the
number of IP addresses that connect to Internet. In such case, only the router will
have Internet access which will dispatch the access through a local sub network
to the service boxes.
This is a part of the local networking and will not be part of the standard delivery
of Connected Services. But, it will be defined with the customer according to its
own IT rules and recommended network hardware.
When such a router is used, there is no need to provide global IP addresses for
the WAN of the service boxes. Only one global address to the service box router
will be used as a gateway for the service boxes.
