How to pfSense.
So, you’ve decided to ditch that POS ISP provided router, or just literally anything marketed towards consumers and have installed pfSense, so.. what now?
The following will be a guide on how to create, manage and understand both firewall rules and NAT in pfSense. I get asked a lot of questions daily and I thought this should be useful for those that are either new to pfSense or want to understand what they’re doing when they create rules.
This guide is not just for pfSense, it’s just what I use and is extremely popular so I’m doing a post about it. A lot of the fundamentals and methodology will carry over to many other devices/software.
In this post, I will try and explain why these steps are being taken and add some networking 101 into the mix as well.
