Zeroshell or pfSense Firewall/Router
I am looking at using one of the firewall/router distributions for home use, but i need some help deciding which one or even alternatives?
My thoughts are pfSense because it is x86_64 compatible and has a larger functionality than Zeroshell combined with a longer active base. As well as being BSD which is known for security.
Two factors i want to account for are the computer that it will be installed on is currently a functional desktop computer which i wouldn't be able to lose for pure firewall functionality. I.e I still need to be able to use the PC as a desktop.
I am not sure how this would work to be honest. pfSense for example can be installed on the harddisk which in that situation would require it to be running in order for it too function??
The alternative is a VM or live CD but again i don't exactly have CD drives to throw around to a dedicated liveCD. A VM could work but will this protect the host operating system or just the guest?
The distro is compatible with existing modems and routers. Obviously this one is more configuration settings.
Lastly i don't want it to be resource intensive. A router/ firewall chewing up 50% of your RAM isn't exactly what i call a firewall/ router more like bloatware. lol :P
The main purpose of this isn't so much for networking but more for added security.
The ideal situation would be a dedicated low-end machine. While this could be done, spending $500 on a low-end machine isn't worth it, when there are several other networking components (and non-computer related stuff) that could be improved etc...
