4.4.

Attack from remote

An attack from remote, meaning from outside the local REF network, should
be prevented. Therefore, unauthorized users should not be able to get access
to REF 542plus. A remote attack is only possible when the devices are
connected to company intranet or Internet. Installing the IPSec function is
recommended.

4.5.

Number of devices allowed per subnet

The number of devices per subnet is limited. The limitation is set to 254
devices.

The practical subnet size should be defined by the application and have a
practical size of 10 devices. In case a GSM Modem is connected, one device
per total network is sufficient.
