9.7.5 Use A-Network ports for WAN (uplink) connection
A-Network interfaces can also be used as the enterprise interface whether in 1-Network or 2-Network
mode. Either of the B-Network ports can be used to connect to other devices in daisy-chain configuration.
The example in the figure below shows port A1 on the port forwarding XIO connected to the corporate
WAN (2). The field devices connect to port B2. In this scenario, local access to the field devices attached
to the port forwarding XIO will need a connection to an available port on any of these devices (see
connection of laptop 5). Connecting to the port forwarding XIO directly (see connection of laptop 4)
provides access only to that XIO, since the A-Network ports and B-Network ports are in separate logical
networks.
