5.4 Internet Connectivity

Connection using a local 3G router
In some case it is not easy or not recommended by the customer to connect the
Service box to the existing Internet access. It is then possible to connect the service
boxes locally to a 3G router with local customer contracts.

The connection with 3G router usually doesn't include Proxy server and can be
also completed with a firewall if required.
Traffic Volume
The service boxes are doing only outbound communication (from box to ABB
server) to setup the secure tunnel connection. This connection must be kept open
and secure by constant "keep alive" ping and secure key renewal.
The estimated traffic for each box is estimated to 250 Mb a month in average.
This is not important for normal Internet connection but need to be taken into
account for 3G connection where the Internet connection paid by the customer is
usually volume based. When a Gateway is used, consider the volume of traffic
from multiple controllers as these controllers are communicating through the
Gateway Service Box.
IP Mapping
The service boxes would require an IP address on the WAN port and a gateway
and a DNS to access Internet. This need to be configured with the customer to
match its global IP mapping with either a Global IP or local IP with intermediate
router
The configuration of the WAN port can be done in the Service box either statically
by entering the IP address gateway and DNS, or through a DHCP server.
Proxy Server
The connection to Internet is facilitated if there is no need to go through a proxy
to access Internet. It is then recommended to ask if the customer could provide a
direct Internet access which could be dedicated to the service boxes.
