Firewall Module

This guide will walk you through the steps to configure the TEG firewall module, allowing you to block specific ports and disable ICMP Timestamp (ping) responses.

Step 1: Access the Module Configuration Page

  • Login to the TEG web interface.

  • Navigate to the firewall module's configuration page by clicking Settings menu on left and then selecting Firewall under Modules.

Step 2: Enter the Module Name

  • In the "Name" field, enter the desired name for your firewall module. By default, this field is set to "Firewall."

Step 3: Block Specific Ports

  • In the "Block specific ports" section, you can enter the ports you wish to block.

    • Ports should be separated by commas.

    • Example: To block ports 22 (SSH), 25 (SMTP), and 443 (HTTPS), you would enter: 22, 25, 443.

Step 4: Disable ICMP Timestamp (ping)

  • To enhance security, you can disable ICMP Timestamp responses.

    • Check the box labeled "Disable ICMP Timestamp (ping)".

    Disabling ICMP Timestamp responses prevents attackers from determining the exact time on your machine, which can help protect against time-based attacks.

Step 5: Save Your Configuration

  • Once you have entered the desired settings, click the blue "SAVE" button at the bottom right corner of the page.

  • If you wish to discard your changes, click the "CANCEL" button at the bottom left.

  • To delete the module entirely, click the red "DELETE MODULE" button at the top right of the page.
