# 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.
