Our dedicated servers customers can add another layer of security to their IoT devices.
If IP whitelisting is enabled on the dedicated server, the firewall on the server blocks all connections except those initiated from the list of addresses.
To enable IP whitelisting go to your forwarding servers page and from there you can enable ip whitelisting for each of your servers by clicking on the IP whitelisting switch:
Once the switch is enabled the firewall will be activated your forwarding server and it will block any attempt to reach the device.
To see the list of whitelisted IP addresses click on the list icon next to the switch which will take you to the list for the selected server.
The IP whitelist page will show you the list of all whitelisted IP addresses.
You can enter just the IP address or you can add the subnet mask in both formats - as an integer or in dotted decimal form.
