Ship your pfSense firewall logs using Filebeat to your Logit.io Stack
Configure a pfSense firewall to ship logs via Filebeat to your Logit.io stacks via Logstash.
Follow this step by step guide to get 'logs' from your system to Logit.io:
Step 1 - Install Filebeat
- Windows
- Linux
- macOS
- DEB
- RPM
To get started you will need to install filebeat. To do this you have two main options:
- Choose the filebeat ZIP file (Windows ZIP x86_64) or
- Choose the Microsoft Software Installer MSI file (Windows MSI x86_64 (beta))
If you have chosen to download the zip file:
- Extract the contents of the zip file into C:\Program Files.
- Rename the extracted folder to filebeat
- Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
- From the PowerShell prompt, run the following commands to install filebeat as a Windows service:
cd 'C:\Program Files\filebeat'
.\install-service-filebeat.ps1
If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:
PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1
For more information about Powershell execution policies see here
If you have chosen to download the filebeat.msi file:
- double-click on it and the relevant files will be downloaded.
At the end of the installation process you'll be given the option to open the folder where filebeat has been installed.
- Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
- From the PowerShell prompt, change directory to the location where filebeat was installed and run the following command to install filebeat as a Windows service:
.\install-service-filebeat.ps1
If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:
PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1

Step 2 - Configure pfSense Logging
Configure the pfSense firewall to log to a syslog server running Filebeat:
On your pfSense firewall interface navigate to "Status" -> "System Logs" -> "Settings"
In Settings under the General Logging Options set the log message format to syslog(RFC 5424, with RFC 3339 microsecond-precision timestamps)
In Settings under Remote Logging Options ensure the following configuration:
- Enable Remote Logging: Enabled
- Source Address: Default (any)
- IP Protocol: IPV4
- Remote Log Servers: FILEBEAT-IP-ADDRESS:514
- Remote Syslog Contents: Everything
Step 3 - Configure Filebeat.yml
The configuration file below is pre-configured to send data to your Logit.io Stack.
Copy the configuration file below and overwrite the contents of the Filebeat configuration file typically located at /etc/filebeat/filebeat.yml
# ============================== Filebeat inputs ===============================
filebeat.inputs:
- type: udp
max_message_size: 10MiB
host: "0.0.0.0:514"
enabled: true
fields:
type: pfsense
fields_under_root: true
encoding: utf-8
ignore_older: 12h
# ================================== Outputs ===================================
output.logstash:
hosts: ["your-logstash-host:your-ssl-port"]
loadbalance: true
ssl.enabled: true
If you’re running Filebeat 7, add this code block to the end. Otherwise, you can leave it out.
# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat
If you’re running Filebeat 6, add this code block to the end.
# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry
It’s a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com is a great choice.
Step 4 - Validate configuration

Step 8 - pfSense Overview
The pfSense firewall is designed to offer advanced network security features for enterprise environments by safeguarding against cyber threats and unauthorized access. In order to effectively monitor and analyze network activity, it is crucial to have a dependable and efficient log management solution. The pfSense firewall generates logs that record important details about network traffic, threats, and user activity.
To manage these logs efficiently, organizations can employ Filebeat, an open-source shipping tool, to transfer logs from pfSense firewalls to various destinations such as Elasticsearch, Logstash, and OpenSearch. Filebeat is widely used due to its reliability and minimal memory footprint. It is also compatible and easy to use.
To transfer pfSense firewall logs to Filebeat, organizations can configure the firewall to forward logs to a syslog server and then utilize Filebeat to collect and forward log data to Elasticsearch or other destinations. This process involves configuring a syslog server to receive the logs, configuring the firewall to send logs to the syslog server, and configuring Filebeat to collect and forward the logs from the syslog server to Elasticsearch or other destinations.
In summary, utilizing Filebeat to send pfSense firewall logs to various destinations, including Elasticsearch, Logstash, and OpenSearch, is a dependable and effective log management solution. By configuring the firewall to forward logs to a syslog server and utilizing Filebeat to collect and forward the logs to Elasticsearch or other destinations, organizations can gain insights into network traffic, threats, and user activity, and take action to protect their networks against cyber threats and unauthorized access.
