I wish these things were still in production. It's the perfect firewall/router for small businesses. I've installed probably 40-50 of these things over the years and pick them up when I need them, although they're getting harder and harder to find. Also note that most do not have updated firmware, so they may not be accessible with modern browsers. The last thing I did was be accessible from an old WindowsXP box running a CNC machine. Once the updated firmware was installed, I was able to access it anywhere.
