As a trusted supplier of the Hirschmann RS20, I understand the importance of proper firewall configuration to ensure the security and optimal performance of your network. In this blog post, I'll guide you through the process of configuring the firewall settings of the Hirschmann RS20, providing you with step - by - step instructions and valuable insights.

Understanding the Hirschmann RS20 Firewall

The Hirschmann RS20 is a high - quality industrial switch that comes with a robust built - in firewall. This firewall is designed to protect your network from unauthorized access, malicious attacks, and data breaches. It allows you to control the flow of network traffic based on various criteria such as source and destination IP addresses, ports, and protocols.

Prerequisites

Before you start configuring the firewall settings of the Hirschmann RS20, make sure you have the following:

  1. A stable network connection to the Hirschmann RS20 switch.
  2. Login credentials (username and password) to access the switch's web - based management interface.
  3. A basic understanding of network concepts such as IP addresses, ports, and protocols.

Step 1: Accessing the Web - Based Management Interface

To configure the firewall settings, you first need to access the web - based management interface of the Hirschmann RS20. Follow these steps:

  1. Connect your computer to the same network as the Hirschmann RS20.
  2. Open a web browser (such as Chrome, Firefox, or Safari).
  3. In the address bar, enter the IP address of the Hirschmann RS20. This IP address was usually set during the initial installation of the switch.
  4. Press Enter. You will be prompted to enter your username and password. Enter the correct credentials and click Login.

Step 2: Navigating to the Firewall Configuration Section

Once you are logged in to the web - based management interface, you need to locate the firewall configuration section. The exact location may vary depending on the firmware version of your Hirschmann RS20, but usually, you can find it under the "Security" or "Firewall" tab.

Step 3: Defining Firewall Rules

Firewall rules are the heart of the firewall configuration. These rules determine which network traffic is allowed and which is blocked. Here's how you can define firewall rules on the Hirschmann RS20:

  1. Click on the option to create a new firewall rule.

  2. In the rule creation window, you will need to specify several parameters:

    • Source: This is the IP address or range of IP addresses from which the traffic originates. You can either enter a single IP address or use the CIDR notation to specify a range.
    • Destination: Similar to the source, this is the IP address or range of IP addresses where the traffic is going.
    • Protocol: Select the protocol (such as TCP, UDP, or ICMP) that the traffic uses.
    • Port: If applicable, enter the port number or range of port numbers for the traffic.
    • Action: Choose whether to allow or block the traffic based on the specified criteria. For example, you may want to block all incoming traffic from an unknown IP address range.
  3. After filling in all the necessary parameters, click Save to create the rule. You can repeat these steps to create multiple rules as per your network security requirements.

Step 4: Ordering Firewall Rules

The order of firewall rules is crucial because the Hirschmann RS20 evaluates the rules from top to bottom. If a traffic packet matches a rule, the action specified in that rule is applied, and the packet is not evaluated against the remaining rules. Therefore, it's important to order your rules in a logical way. For example, you may want to place the most restrictive rules at the top.

Step 5: Testing the Firewall Configuration

After configuring the firewall rules, it's essential to test if the configuration is working as expected. You can use network diagnostic tools such as ping and traceroute to test the connectivity from different sources to various destinations. If the traffic is being blocked or allowed as per your rules, then your firewall configuration is correct. Otherwise, you may need to review and adjust your rules.
