      Table 2 Configuring public network access for OpenSearch Dashboards

      Parameter

      Description

      Bandwidth

      Bandwidth for accessing OpenSearch Dashboards from the public network.

      Value range: 1 Mbit/s to 200 Mbit/s

      Configure Whitelist

      Control OpenSearch Dashboards public network access using a whitelist.

      • If a whitelist is configured, only IP addresses that are on this whitelist can access the cluster's OpenSearch Dashboards over the public network.

        Click + Add. In the displayed text box, enter IP addresses or CIDR blocks that are allowed to access the cluster's OpenSearch Dashboards console from the public network. Separate them using commas (,). Each value must be unique. An example of valid values: 192.168.1.1,10.0.0.0/24. Examples of invalid values: 0.0.0.0, xx.xx.xx.xx/0, 172.16.0.0-172.16.255.255, non-standard formats (e.g., 192.168.1), and duplicate values.

      • If no whitelist is configured, all public IP addresses can access the cluster's OpenSearch Dashboards console. However, this can be a security risk and should be avoided.
    3. Click OK to confirm the settings.
