Building a pfSense Firewall
 

Today I would like to share some of my experiences with you in regards to firewalls, as this is an area of computing that is often overlooked. Far too many people rely simply on the Windows firewall and whatever filtering is done by your router. You’re being left in the dark about what is actually being filtered or done, can you even trust this? I hope after today I can help you take more control over your own network and its security.
