Adding or Modifying Firewall Rules

When you create a pgEdge Cloud cluster, you can provide firewall rules that define the IP addresses or CIDR blocks that are allowed to connect to your cluster. To add or modify a cluster's firewall rules, highlight the name of a cluster in the navigation tree and select Update Firewall Rules from the Actions (opens in a new tab) drop-down menu.

The Firewall Rules popup displays the currently defined rules for your cluster. You can click the + Add Firewall Rule bar to open a new line (as shown below) and add a new firewall rule, or modify the current rules:

To add or modify a firewall rule:

• Use the Type selector in the left column to specify the incoming connection type. You can create a rule that connects with:

  • A PostgreSQL client like pgAdmin or psql on port 5432.
  • An SSH client on port 22.
  • An HTTPS client on port 443.

• Use the Sources field in the right column to add or remove the IP address(es) or CIDR block(s) (opens in a new tab) that will be allowed to connect via the connection Type specified in the left column.

  • To remove an address, click the X to the right of the address in the Sources field.
  • To add an address, click in the Sources field and select from the predefined options, or type directly in the field. After entering each address, hit Enter to confirm the addition; you can then add another address to the Sources field, or select + Add Firewall Rule to open another line for entries.

When you're finished, select Update Firewall Rules to modify your cluster's firewall. While the firewall is being modified, a blue dot to the left of the cluster name indicates that the changes are being applied. During this time, your cluster remains available for connections, but you must wait to make further modifications to the cluster definition.
