I seriously doubt that you can find anything in the trash that isn't seriously oversized. In 2001, i ran an OpenBSD 2.7 firewall with ipf(4) on an Intel 486-SX25 (25 MHz) with 24 MB (not GB!) RAM, a system disk of 100 MB (not GB!) and a /var/ disk of another 100 MB. The about ten concurrent users were happy with it for years. OK, that would no longer work because the SX25 had no numerical coprocessor which is now required to run OpenBSD, and it required some fiddling to fit the system installation into 100 MB. But it always routed the traffic fast enough. Currently, one of my office firewalls runs on: - CPU: AMD-K6 234 MHz (yes, a quarter of a GHz) - RAM: 128 MB (yes, an eigth of a GB) - HD: ATA (not SATA!) UDMA-2, 3 GB (not 300 GB!) The only reason the machine is *THAT* large is that at the time it was selected, we no longer had any smaller dismantled desktop machines in the trash. I don't have the slightest doubt that a much smaller machine would also be fine - certainly with half of everything, like 100 MHz, 64 MB RAM, 1 GB disk. And since then, i'm too lazy to pull something newer from the trash to replace it - because it just works. As a matter of fact, i'm sending this email over it... Yours, Ingo
