Hi, I am new to pfSense experience. My friend told me about pfsense but I have no idea what it is and how it operates?
It is an OpenSource x86 firewall distribution based on FreeBSD as the underlying OS.
Is it a paid service? or a platform?
He is telling you about his firewall, and nothing more?
He said something about securing the network. How pfsense can help me in that?
A router does usually only SPI/NAT and a firewall is working with firewall rules for allow and deny
or plain passing through the entire network traffic. Or in short a router is routing between one and another or
more networks and a firewall is separating one from another or more networks. As today this border will be for
sure becoming blurred more and more.
