By default the Gateway Inverter will detect and recommend an IP/Subnet from which external devices are
allowed through the Inverter Gateway Firewall. For security purposes the user is encouraged to enter the most
restrictive value, with preference given to the specific IP address of the external device (DAS). Up to two
IP/Subnet pairs can be entered on each gateway.
NOTICE !
CYBER SECURITY! Configuring an entire IP subnet will not only allow the desired DAS device but would also
enable all the other devices (authorized or unauthorized) in the subnet to be able to access the Inverter cluster
LAN. Use the most restrictive settings possible.
