If anyone recalls I posted a link to a couple 4 port embedded mini-pc's a few weeks back. I loaded ClarkConnect v5 on one and smoothwall on the other. They didn't come with power bricks but I had one that was spec'd right and ordered another from geeks.com for $13.
I just switched out my DDWRT WRT150N router with the little clarkconnect box and I have to say I'm very impressed so far. It's a 600MHz Pentium-M celeron box with 1GB ram. I've got content filtering running, extensive firewall, IDS system, HTTP server, Quake 3 server, and torrent server running. I've played around with a VOIP wondershaping script, QOS, etc. My speedtests at multiple sites jumped from download of 3900 KB/s to 8834.9 KB/s Upload speed went from 220 kbps to 570 kbps I'm amazed that there could be such a huge difference. I haven't had time to test the smoothwall box as much, but I prefer its various plugins to the more limited firewall/NIDS capabilities of the clarkconnect box. Maybe I'll get motivated at some later time to write a small review, hehe lopaka
