6.7 Notes on using gateways in a network
With this device, it is possible to establish a connection and to configure the device by way of a gateway.
NOTE
The public IP address of the device must be known in order to communicate across
gateway boundaries. Automatic detection of the device is only possible in the local
network.
To establish the connection, use the options in the selection list of available devices.
To do this, set your PC and the
device
as follows:
PC:
The gateway of the PC's local network (Gateway 1) must be set in the configuration of the
network adapter.
Device:
The gateway of the device's local network (Gateway 2) must be set in the network
configuration.
The following items must be kept in mind when an address conversion using NAT (Network Address
Translation) is being used for at least one of the gateways:
To connect the device using the
Application Suite
, you must specify the public address and port
number of the
gateway
to which the device is connected (Gateway 2).
A separate port for communications must be used in the device settings.
You can find this setting under
Device → Device settings → IP address / Network
. Change the
Port
setting from
Standard
to the
desired port number
.
Keep in mind that changes to the network settings of the device are only valid in the local network. If
necessary, make sure that the NAT settings of the gateway are also configured to make
communication possible.
