Best Linux firewall
- 
 @RoguePacket ah ha. zentyl I have heard of but not used. 
- 
 Zentyl is really an SBS style server project. A kitchen sink sorta mish mash. Not an optimized firewall. 
- 
 @scottalanmiller Yes, have used it in one of my freelance project. They wanted an AD replacement as they couldn't afford windows licensing. After some research, I tried Zentyal. It was a real good alternative for Windows AD. Got a decent desktop machine, installed Zentyal, configured as main DC, joined all clients machines from 3 offices, (all nearby, and has shared connection from their main office). Also enabled jabber server+file server. All offices are using this without any issues. AD+Chat+File Server!  
 If am not mistaken, its Ubuntu based. Even though it has quite a lot of features including firewall, I never used it as a firewall.
- 
 @scottalanmiller so was ClearOS.

 I'd recommend pfSense. I'm only an intern level tech person, and I find it fairly easy to work with.

 Really only the paid for version of Untangle. I've used Untangle and it is a seriously weak product.

Only $50/month and you get content filtering, multi-WAN, IPS, antivirus, application-level control, bandwidth shaping, and more. $50/mo is a ton for an SMB. Considering you have to buy hardware to put the appliance on, that's $600/year. You can get some pretty nice systems for that price. 
- 
 For that price you could be in a fully supported Meraki, for example, and that's far from a cheap device. It would take less than two years to pay it off assuming you were running your Untangle on free hardware that you already owned.

 For only $99, you can have one of these running Vyatta: http://www.amazon.com/EdgeRouter-ERLite-3-512MB-Ethernet-Router/dp/B00CPRVF5K

 $89 plus shipping from Baltic networks, so depending on your Amazon shipping rates. That may be a better place to buy it. 
 I love the ERL. I have 10 of them in production around various clients.http://www.balticnetworks.com/manufacturers/ubiquiti/edgemax-routers.html

- 
 @scottalanmiller the ERL and ERPOE are 1 billion packets per second (pps). The ER is 2 billions pps and the ER Pro is 2+ billion pps. This is all according to their spec sheets. I have never stressed tested anything. My clients couldn't stress and ERL if they tried.

 I wish that there was a ERL that was rack mount. That would be way better.
