Firewalls - Linux based - Errrrr! Have to save money!
As of right now my 70 person node network is behind a namebrand (which btw runs great for what it is). I currently set up a IPcop firewall at my house and that also works great and the most important part its free. I started thinking way cant I use this at work (or something similar) - I have been looking at smoothwall corp 5 and endian firewalls for work. There are a few requirements that i need that being smtp communication, vpn, anti spam, anti virus, intrusion detection, web filtering and content filtering, whitelist, black lists, you know all the cool features - Redundant -
So the question is what are you using/recommend (free) for a linux firewall? I know some of you might say well I dont what to tell this guy what I use at work for security reasons. I am just looking for a way to def save money, but, have all the features that I am looking for. Any recommendations?
