Firewall management

The Firewall management section includes two lists on a single page that will present the context of each file stored. This tutorial will show you how to add inbound IP addresses and outbound ports to incorporate changes to the H2O AI Managed Cloud (HAMC) environment.

Click Firewall management on the left-navigation bar to open the Firewall management page.

Inbound IPs​

Add inbound IPs​

The H2O AI Managed Cloud Admin Center enables you to add a list of specific inbound IPs to allow inbound traffic to your HAMC. By configuring inbound IPs, you can control who and what has access to your cloud environment and reduce the risk of unauthorized access.

For example, if you want to grant access to a specific partner or vendor, you can add their IP address to the list of inbound IPs. It ensures that only traffic generated from the specified IP address is allowed to enter your HAMC environment and interact with your resources. The default configuration of inbound IPs in firewall management is 0.0.0.0/0, which allows access from any IP address.

To add an inbound IP, consider the following instructions:

  1. Click Add in the Inbound IPs section.
    A side panel appears.
  2. In the Inbound IP(s) text box, enter your inbound IP address, for example: 176.230.223.145/32.
    Note

    Enter a valid public-facing IP address with a subnet mask.

  3. Click Add IP.
    The IP address appears in the list of inbound IPs.
  4. Close the side panel, and click Apply changes in the top-right corner. apply changes button

Delete inbound IPs​

To delete inbound IPs, consider the following instructions:

  1. Select the inbound IP(s) you want to delete.
  2. Click Delete in the Inbound IPs section. click Delete button
  3. In the confirmation dialog, click Yes.
  4. Click Apply changes in the top-right corner.

Outbound Ports​

Add outbound ports​

The H2O AI Managed Cloud Admin Center allows you to select a protocol and add a list of specific outbound ports to enable outbound traffic from your HAMC. Configuring outbound ports provides additional security to your HAMC environment by limiting the outbound traffic only to the necessary ports and ensuring your cloud environment communicates with authorized services only.

For example, if you want to pull data from a SQL Server database into HAMC, you need to enable outbound traffic on port 1433.

The following ports are open by default:

  • Port 1433 for SQL Server
  • Port 1521 for Oracle Database
  • Port 80 for HTTP protocol
  • Port 443 for HTTPS protocol
  • Port 5432 for PostgreSQL
  • Port 5439 for Amazon Redshift

To add an outbound port, consider the following instructions:

  1. Click Add in the Outbound ports section.
    A side panel appears.
  2. In the Protocol drop-down, select a protocol.
    note

    The default protocol is set to TCP.

  3. Under Outbound Port(s), enter your outbound port(s) used by the selected protocol.
    Note
    • Enter a valid port.
    • Ports should be in the range of 1-49151.
    • You can add multiple ports used by the selected protocol as a comma-separated list.
  4. Click Add port.
    The outbound port and the protocol appear in the list of inbound IPs.
  5. Close the side panel, and click Apply changes in the top-right corner. apply changes button

Delete outbound ports​

To delete outbound ports, consider the following instructions:

  1. Select the outbound port(s) you want to delete.
  2. Click Delete in the Outbound ports section. click Delete button
  3. In the confirmation dialog, click Yes.
  4. Click Apply changes in the top-right corner.
