# Manage access
By default, all incoming connections to the database instance are blocked as a security measure.
***
The firewall applies to the entire database instance, not just specific databases or users. The firewall also applies to the monitoring URL.
## Managing database access using the control panel
In the **Firewall** section of the overview, you need to add the IP addresses or IP ranges that should be allowed to connect to the database. Click **Manage access** to enter your IP addresses.
In the dialog box that opens, enter your IP addresses or IP ranges, separated by commas. In this example, we allow the entire IP range 203.0.113.0/24 and a single IP address 128.66.1.43. Once you’ve entered your IP addresses, click **Update**.
## Managing database access using the API
Use the [database/updateallowlist](https://github.com/GleSYS/API-docs/wiki/API-Documentation#databaseupdateallowlist) endpoint to manage database access using the [API](/platform/control-panel/api.md).
