Concept
Firewall
You can configure the devices that are allowed to communicate with the automation server to prevent connection attempts from unauthorized devices. The IP addresses of the devices that are allowed to communicate with the automation server are added to the whitelist.
The devices IP addresses are specified in the whitelist by their IP addresses or by specifying an address mask that includes the devices address. This makes it possible to add a mask of IP addresses to the whitelist using CIDR notation. The whitelist can be edited at any time.
The default whitelist, 0.0.0.0/0, allows all devices to communicate with the automation server. When you add devices to the whitelist, only the devices on the whitelist can communicate.
The maximum allowed size of a whitelist is 2048 bytes, approximately 100 devices.
If you have a number of automation servers that uses the same whitelist configuration, you can configure all automation server at the same time.
