pfSense
As a network administrator, having a firewall and router in place is essential. When we talk about setting up a firewall, we have the option to either simply install a preconfigured firewall from any vendor or set up our own firewall system.
pfSense is one amazing software distribution, if you wish to set up your own firewall from scratch. It is an open source distribution based on FreeBSD and is specially designed to be used as a firewall that can be managed easily through a web interface.
Getting ready
- Download pfSense from this link: https://www.pfsense.org/download/mirror.php?section=downloads.
- Choose the correct computer architecture and platform as per your requirement.
- After downloading pfSense, burn the ISO file to CD/DVD media, or you can even create a live bootable USB media.
- We also need a system with two network interface cards to install and configure pfSense.
Note
This system will be dedicated to the firewall functionality and will not be usable for any other computing task...
