Once you're logged in, you'll be greeted with the pfSense dashboard, which provides an overview of your system's status, including CPU usage, memory usage, network traffic, and system logs.

From the dashboard, you can access all of the configuration options. The first thing you'll probably want to configure is your WAN interface. This involves setting the IP address, gateway, and DNS servers for your internet connection. If you're using DHCP, pfSense can automatically obtain these settings from your ISP. If you have a static IP address, you'll need to enter it manually. Next, you'll want to configure your LAN interface. This involves setting the IP address and subnet mask for your local network. You'll also want to enable the DHCP server on the LAN interface so that devices on your network can automatically obtain IP addresses. Then comes the firewall rules. This is where you define the rules that control network traffic. pfSense uses a stateful firewall, which means that it tracks the state of each connection and automatically allows return traffic for established connections. You can create rules to allow or block traffic based on source and destination IP addresses, ports, and protocols. It's important to create firewall rules that are both secure and allow legitimate traffic to pass through. Start with a default deny policy, which blocks all traffic by default, and then create rules to allow specific types of traffic.

You'll also want to configure any other features you need, such as VPNs, intrusion detection, or traffic shaping. The configuration process for these features varies depending on the specific feature. pfSense has extensive documentation and a large community of users who can provide assistance if you get stuck.
