History Since some time our company Eurospider was using home-grown firewalls based on OpenBSD. Our administrator at this time (Mihai Barbos, https://github.com/mbarbos) decided to use Portwell NAR-2054 hardware with 3 up to 5 ethernet ports and run a customized OpenBSD on it. Now the company firewall is a Soekris net6501 as the Portwell firewalls started to become a little bit rusty. There is still one Portwell left in use for a control network serving access to remote management consoles of our servers.
Found a really nice new router appliance based on OpenBSD 6.0, http://securityrouter.org. I’m still missing some features like a split-horizon DNS, so I will not abandon the script-based project http://github.com/andreasbaumann/OpenBSD-firewall just for now.
