Configuring Basic Settings

Now that you're in the pfSense web interface, let's configure some basic settings to get your network up and running. This includes setting up your WAN and LAN interfaces, configuring DHCP, and setting up basic firewall rules.

WAN Interface Configuration

The WAN (Wide Area Network) interface is the connection to the internet. You'll need to configure this interface with the correct settings provided by your internet service provider (ISP). This might include setting a static IP address, using DHCP, or entering PPPoE credentials.

  1. Access WAN Settings: In the pfSense web interface, go to Interfaces > WAN. Here, you’ll see the settings for your WAN interface.
  2. Configuration Type: Choose the appropriate configuration type based on your ISP’s requirements. If your ISP provides a static IP address, select Static IPv4. If they use DHCP, select DHCP. If they use PPPoE, select PPPoE.
  3. Enter Details: Enter the required details, such as the IP address, subnet mask, gateway, and DNS servers if you’re using a static IP. If you’re using DHCP, simply ensure that the Enable DHCP client option is checked. For PPPoE, enter your username and password provided by your ISP.
  4. Save Changes: Once you’ve entered all the necessary information, save the changes. pfSense will apply the new settings and attempt to establish a connection to the internet.

LAN Interface Configuration

The LAN (Local Area Network) interface is the connection to your internal network. This is where you'll configure the IP address and subnet mask for your local network, as well as the DHCP server settings.

  1. Access LAN Settings: In the pfSense web interface, go to Interfaces > LAN. Here, you’ll see the settings for your LAN interface.
  2. IP Address and Subnet Mask: Set the IP address and subnet mask for your local network. The default is usually 192.168.1.1/24, but you can change this to any private IP address range you prefer, such as 10.0.0.1/24 or 192.168.0.1/24. Make sure to choose an address that doesn’t conflict with any other devices on your network.
  3. DHCP Server: Enable the DHCP server to automatically assign IP addresses to devices on your network. Go to Services > DHCP Server and select the LAN interface. Configure the IP address range for the DHCP server to assign. For example, if your LAN IP address is 192.168.1.1 and subnet mask is /24, you might set the range from 192.168.1.100 to 192.168.1.200.
  4. Save Changes: Save the changes to apply the new settings. Your devices should now be able to obtain IP addresses automatically from the pfSense DHCP server.

Basic Firewall Rules

Firewall rules are essential for controlling network traffic and securing your network. By default, pfSense blocks all incoming traffic and allows all outgoing traffic. You'll need to create rules to allow specific types of traffic to enter your network.

  1. Access Firewall Rules: In the pfSense web interface, go to Firewall > Rules. Select the LAN interface to create rules for traffic originating from your local network.
  2. Create a New Rule: Click the Add button to create a new rule. You’ll need to define the action (pass or block), interface, protocol, source, and destination for the rule.
  3. Example Rule: To allow devices on your LAN to access the internet, create a rule with the following settings:
    • Action: Pass
    • Interface: LAN
    • Protocol: Any
    • Source: LAN net
    • Destination: Any
  4. Save Changes: Save the rule to apply the changes. You can create additional rules to allow other types of traffic, such as allowing incoming connections to a web server or allowing specific ports for gaming.

Advanced Configuration

Once you have the basic settings configured, you can explore some advanced features of pfSense to further enhance your network security and performance. This includes setting up a VPN, configuring traffic shaping, and setting up intrusion detection.

VPN Setup

Setting up a Virtual Private Network (VPN) allows you to securely connect to your network from remote locations or create secure connections between different networks. pfSense supports various VPN protocols, including OpenVPN and IPsec.

  1. Choose a VPN Protocol: Decide which VPN protocol you want to use. OpenVPN is a popular choice due to its flexibility and security. IPsec is another option, often used for site-to-site VPN connections.
  2. Install OpenVPN: If you choose OpenVPN, go to System > Package Manager and install the OpenVPN Client Export Utility package. This package makes it easier to create client configurations for OpenVPN.
  3. Configure OpenVPN Server: Go to VPN > OpenVPN > Servers and create a new OpenVPN server. Configure the server settings, such as the interface, protocol, port, and encryption settings. You’ll also need to generate a certificate authority (CA) and server certificate.
  4. Configure OpenVPN Clients: Use the OpenVPN Client Export Utility to create client configurations for your users. These configurations will allow them to connect to the VPN server securely.

Traffic Shaping

Traffic shaping allows you to prioritize certain types of network traffic over others, ensuring that critical applications receive the bandwidth they need. This can be useful for improving the performance of VoIP calls, video conferencing, or online gaming.

  1. Enable Traffic Shaper: Go to Firewall > Traffic Shaper and enable the traffic shaper. You’ll need to configure the interfaces and bandwidth limits for your network.
  2. Create Queues: Create queues to prioritize different types of traffic. For example, you might create a high-priority queue for VoIP traffic and a low-priority queue for file downloads.
  3. Create Rules: Create firewall rules to direct traffic to the appropriate queues. You can use the firewall rules to match traffic based on source, destination, protocol, and port.

Intrusion Detection

Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) help you monitor your network for malicious activity and automatically block or prevent attacks. pfSense integrates with Suricata and Snort, two popular open-source IDS/IPS systems.

  1. Install Suricata or Snort: Go to System > Package Manager and install either the Suricata or Snort package.
  2. Configure the IDS/IPS: Configure the IDS/IPS settings, such as the interface to monitor, the rulesets to use, and the actions to take when an intrusion is detected. You can download pre-built rulesets from various sources or create your own custom rules.
  3. Monitor Logs: Monitor the IDS/IPS logs to identify potential security threats and take appropriate action. You can use the pfSense web interface to view the logs or configure email alerts to notify you of critical events.

Troubleshooting Common Issues

Even with careful setup, you might encounter some issues. Here are a few common problems and how to troubleshoot them:
