  2. Connecting the Hardware:
    • Connect your internet modem to the WAN port on the Netgate 2100. This is usually labeled as "WAN" or "Internet."
    • Connect a computer to one of the LAN ports. This will be your management interface.
    • Plug in the power adapter and turn on the Netgate 2100.
  3. Accessing the Web Interface:
    • Open a web browser on your connected computer.
    • Type 192.168.1.1 into the address bar and press Enter. This is the default IP address for the Netgate 2100.
    • You might see a security warning about an untrusted certificate. This is normal; you can proceed by clicking "Advanced" and then "Accept the Risk and Continue."
  4. pfSense Setup Wizard:
    • You'll be greeted by the pfSense setup wizard. Follow the prompts to configure basic settings like:
      • Hostname: Choose a name for your Netgate 2100.
      • Time zone: Select your correct time zone.
      • WAN Interface Configuration: This is crucial! Choose the correct connection type (DHCP, Static IP, PPPoE) based on your internet service provider's requirements. If you're unsure, DHCP is often the easiest option.
      • LAN IP Address: You can usually leave this as the default (192.168.1.1), but you can change it if needed.
      • Admin Password: This is super important! Set a strong, unique password for the administrator account. Don't use the default!
  5. Completing the Setup:
    • Once you've completed the wizard, the Netgate 2100 will reboot.
    • After the reboot, you can log in to the web interface using the username admin and the password you set during the setup wizard.

Troubleshooting Tips:

  • Can't access the web interface? Double-check that your computer is connected to the LAN port and that you've entered the correct IP address (192.168.1.1). Also, make sure your computer is set to obtain an IP address automatically (DHCP).
  • WAN interface not getting an IP address? Make sure your modem is properly connected and powered on. If you're using DHCP, try releasing and renewing the IP address on the WAN interface within the pfSense web interface. If you're using a static IP address, double-check that you've entered the correct information provided by your ISP.

Configuring Your Firewall

Now that you've got the basics covered, let's dive into configuring your firewall. The firewall is the heart of your Netgate 2100, controlling which traffic is allowed in and out of your network. Getting this right is essential for security.

  • Understanding Firewall Rules: Firewall rules are the instructions that tell pfSense how to handle network traffic. Each rule specifies criteria like the source and destination IP addresses, ports, and protocols, as well as the action to take (allow, block, or reject). Rules are processed in order, so the first rule that matches a particular packet is the one that's applied.
  • Default Rules: By default, pfSense blocks all incoming traffic and allows all outgoing traffic. This is a good starting point for security, as it prevents unauthorized access to your network. However, you'll need to create rules to allow specific types of traffic that you want to permit, such as web browsing, email, or VPN connections.
  • Creating Firewall Rules:
    1. Navigate to Firewall > Rules in the pfSense web interface.
    2. Select the interface you want to create a rule for (e.g., WAN, LAN).
    3. Click the Add button to create a new rule.
    4. Configure the rule settings:
      • Action: Choose whether to allow, block, or reject traffic.
      • Interface: Select the interface the traffic is coming from (e.g., WAN for incoming traffic from the internet).
      • Protocol: Specify the protocol (e.g., TCP, UDP, ICMP).
      • Source: Define the source IP address or network. You can use "any" to allow traffic from any source, but it's generally more secure to specify a specific IP address or network.
      • Destination: Define the destination IP address or network. Similar to the source, you can use "any" or specify a specific IP address or network.
      • Destination Port Range: Specify the port range for the traffic. For example, port 80 is typically used for HTTP (web) traffic, and port 443 is used for HTTPS (secure web) traffic.
      • Description: Add a brief description of the rule for your reference.
    5. Click Save to save the rule.
  • Common Firewall Rule Examples:
    • Allowing Web Traffic (HTTP/HTTPS): Create a rule on the WAN interface to allow TCP traffic with a destination port range of 80 (HTTP) and 443 (HTTPS).
    • Allowing SSH Access: Create a rule on the WAN interface to allow TCP traffic with a destination port of 22 (SSH) from a specific IP address or network. Important: Only allow SSH access from trusted networks and consider using key-based authentication for added security.
    • Blocking Specific IP Addresses: Create a rule on the WAN interface to block all traffic from a specific IP address. This can be useful for blocking known malicious sources.
  • Best Practices:
    • Principle of Least Privilege: Only allow the minimum amount of traffic necessary for your network to function. This reduces the attack surface and minimizes the risk of unauthorized access.
    • Regularly Review Your Rules: Periodically review your firewall rules to ensure they are still necessary and appropriate. Remove any rules that are no longer needed.
    • Use Descriptive Descriptions: Add clear and concise descriptions to your firewall rules to make them easier to understand and maintain.
    • Test Your Rules: After creating or modifying firewall rules, test them thoroughly to ensure they are working as expected. You can use tools like ping, traceroute, or nmap to test connectivity and identify any issues.
