How to configure pfSense firewall rules

Firewall rules in pfSense allow you to control traffic entering or leaving your network. Configuring firewall rules is a crucial part of setting up your pfSense installation.

Here is a simple guide on how to create and manage firewall rules in pfSense:

  1. Access the pfSense Dashboard: Log into your pfSense firewall via your web browser (the default IP address is usually unless you’ve changed it). You will be prompted for a username and password. The default credentials are usually ‘admin’ for username and ‘pfsense’ for password unless you’ve changed them.
  2. Access Firewall Rules: From the top menu, go to ‘Firewall’ and then select ‘Rules’. Here you’ll see a list of your network interfaces. By default, you should have at least ‘WAN’ and ‘LAN’.
  3. Choose the Interface: Select the tab of the interface where you want to add the rule. If you’re adding a rule for inbound internet traffic, you’d typically select ‘WAN’. For rules that apply to your local network, select ‘LAN’.
  4. Add a New Rule: Click on the ‘Add’ button to create a new rule. This will open the Firewall Rules editor.
  5. Configure the Rule:
    • Action: Choose what the rule should do. ‘Pass’ allows the traffic, ‘Block’ denies the traffic, and ‘Reject’ denies the traffic and sends back an error.
    • Interface: This should be pre-filled based on the tab you selected earlier.
    • Address Family: Choose ‘IPv4’, ‘IPv6’, or ‘IPv4+IPv6’ based on the type of traffic you want to manage.
    • Protocol: Choose the protocol that the rule should apply to (TCP, UDP, ICMP, etc.).
    • Source and Destination: Specify the source and destination of the traffic. This can be any combination of IP addresses, network addresses, or ports. You can also use aliases to group multiple addresses or ports.
    • Log: Check this box if you want to log packets that match this rule.
  6. Save and Apply Changes: Click on ‘Save’ to add the rule, and then click on ‘Apply Changes’. pfSense will apply the rule immediately.

Remember, rules in pfSense are processed from the top down, with the first match being applied. Therefore, more specific rules should be placed above more general ones. Also, there’s an implicit ‘block all’ rule at the end of the list. If no rule matches the traffic, it will be blocked. You don’t see this rule, but it’s there in the background.

For more advanced configuration, pfSense also allows for rules related to traffic shaping, failover, VPN, etc. Be sure to thoroughly test any rules in a controlled manner before applying them to a production network, as incorrect rules can lead to network outages or security vulnerabilities.

Nmap: A Comprehensive Guide

Nmap, or Network Mapper, is an open-source tool that network administrators use to scan networks. Since its inception in 1997, it has become a standard tool in the field. However, its vast array of features and capabilities means there’s always more to learn. This blog post aims to delve deeper into the usage of Nmap, pushing past the beginner level to further explore its features.

Nmap Fundamentals

Nmap is primarily used to discover hosts and services on a computer network. It achieves this by sending packets to the target host(s) and then analyzing the responses. Through this, Nmap can gather a wealth of information, such as what hosts are available on the network, what services those hosts are offering, what operating systems they are running, what type of packet filters/firewalls are in use, and other characteristics.

Beyond the Basics

For those who are already familiar with basic Nmap scans, such as the simple SYN scan (nmap -sS target), it’s time to look into its more advanced features.

Scripting Engine

One of Nmap’s most powerful features is its scripting engine. Using the Nmap Scripting Engine (NSE), you can automate a wide variety of networking tasks. NSE uses scripts, or short programs, that allow you to explore beyond what predefined Nmap scan types offer.

Scripts can be used in a variety of situations, from advanced version detection to more aggressive scans. For example, the http-title script fetches web page titles from HTTP services (nmap --script http-title target). The scripts are written in the Lua programming language, and the NSE offers a full API for script writers to use.

Decoy Scanning

Decoy scanning is a technique where Nmap sends out decoy packets along with its actual scan packets. To an observer, it seems like the scan is coming from multiple IP addresses rather than just the actual source. This technique can be helpful when you want to hide your IP address during the scan. The syntax for decoy scanning is nmap -D RND:10 [target] (where ‘RND:10’ means to use 10 random decoys).

Idle Scanning

Idle scanning is a stealthy scanning technique that allows the attacker to scan a target without actually sending packets from their own IP address. This technique uses a “zombie” host, which you have determined to be idle, to bounce packets off of in order to scan a target. The command for this is nmap -sI [Zombie IP] [Target IP].

Final Thoughts

Nmap is a complex and powerful tool, and this blog post has only just scratched the surface of its capabilities. It’s important to use Nmap responsibly and ethically, always ensuring you have permission to scan the networks and hosts you are investigating. With a better understanding of advanced Nmap usage, network administrators can be better prepared to secure their networks.

Remember that the best way to learn is to practice. If you’re looking to hone your Nmap skills, platforms like TryHackMe offer excellent learning paths and practical rooms to help you grow as a cybersecurity professional.
