Recently I have been hunting for a firewall to use for in my internal network. Primarily I needed to create a DMZ for some web servers so that they could not access my internal LAN. Also it needed to work with Hyper-V.
After looking at (and trying) a number of options I came across clearOS and I was presently surprised. It ticked all of the major boxes for me in and it was simple to set-up and has a fantastic UI.
So many firewall products have UI’s that are very difficult to use and can take ages to get the simplest firewall rule set-up, simply because finding the correct option takes ages.
In comparison clearOS is a breeze to use. The default set-up comes with a very clean UI which only has a few options, because of this it only takes minutes to get up and running. A lot of vendors could learn a lot from clearOS and how they have implemented their UI. The default set-up quickly provides a firewalled LAN with no fuss, perfect!
When you need to add extra functionality like 1 to 1 NAT, you simply open the clearOS Market Place and add the functionality you want to use. The new functionality loads quickly without a reboot. There are over 100 modules for you to add. So there is no shortage of functionality!!
When configuring your network you have the usual options of External(for you internet connection), LAN (for your internal PC’s), DMZ(for any web servers) but they also add the option of a “Hot LAN” which is mixture of a LAN and DMZ. You can place your servers in the Hot LAN and know that your LAN will be still safe. The Hot LAN is very useful when you don’t have direct access to your public IP’s(mine are hidden behind another router) or need to use NAT.
So not only is clearOS simple to get started, it can easily be expanded to allow for much more complex environments. It’s the best of both worlds!
If you are looking for new firewall you should put clearOS at the top of your list. They also provide hardware with clearOS pre-installed and support(both free and paid).
