  5. Click "Save" to apply the changes.
  6. If you are using a firewall, be sure to allow incoming traffic on the specified SSH port.

Once you have successfully configured the SSH server on pfSense, you will be able to access in a safe way to the server from a remote location using an SSH client. Remember that it is important to follow good security practices, such as using strong passwords and limiting access to authorized users.

4. Steps to establish web access in pfSense

To establish web access in pfSense, it is important to follow a series of steps to ensure correct configuration. Below are the 3 key steps to achieve this:

Step 1: Configuring the web server

The first step is to configure the web server in pfSense. To do this, you must access the pfSense web interface using a web browser and log in with the appropriate credentials. Once inside, you must navigate to the web server configuration section and enable remote access. It is recommended to ensure that you use an SSL certificate to ensure connection security.

Step 2: Opening ports

Once the web server is configured, it is necessary to open the corresponding ports in the pfSense firewall to allow access from the internet. To do this, you must access the firewall rules section and create a new inbound rule that allows traffic through the port used by the web server (usually port 80 for HTTP or port 443 for HTTPS). Additionally, if a web application server is used, the ports necessary for its correct operation must also be opened.

Step 3: Test and Troubleshoot

Once the configuration and opening of ports has been completed, it is recommended to perform web access tests from different devices and locations to make sure everything is working correctly. If you encounter any problems, tools such as the pfSense event log or the command console can be used to identify and resolve possible errors. Additionally, it is important to follow good security practices, such as using strong passwords and regularly updating pfSense software to avoid vulnerabilities.
