Untangle has been our “go-to” firewall for businesses since…geeeze…back with version 5. ( can’t recall back when that was…2005 maybe?) Been a partner with them ever since, have sold/installed a lot of 'em.
Years ago I used to have a hobby…trying a different *nix powered firewall at about 1x a month. Used to use various small form factor business desktops computers at home to install them on…and run my home network on. I recall PFSense back with its first release. And IPCop, m0n0wall, Smoothwall, Endian, Copfilter (a UTM add on for IPCop), ClearOS, Astaro (since bought up by Sophos…and now it’s Sophos UTM), Zentyal, ClarkConnect…yeah lots of fun ones.
But outside of the hobby, chose Untangle for us to resell/install for our clients. Beats the heck out of Sonicwall, Watchguard, Fortinet, and all those “boxed retail” UTM firewalls for businesses.
Anyways…heck of a potent server you have there. We used to run it on full blown 1U rack mount servers at some really large clients. But these days, nice smaller 1U or even fanless mini desktop industrialized units are what we use (like Protectli…an i3 or i5 with 8 or even 16 gigs…overkilll…but cheap).
Lots of people try to compare to PFSense. We’ve done quite a few PF installs for clients also. I call it the “Ferrari of firewall distros”…wicked fast, lean 'n mean. But it’s not a UTM. Yes you can add a couple of almost quasi UTM-ish models…but, it’s not a full UTM like Untangle. Apples and Oranges. Each have their purpose that they excel at.
