Hello, I have a specific goal and am seeking opinions. The goal is to make small, readily-reproducible read-only routing devices. The device will serve either as a gateway or bridge with main functions such as filtering traffic, vpn, potential to graph traffic and the like.
The software will vary, but it will be always be a BSD variant and filtering will be with NPF, IPFW, or PF. The question is about hardware: 1) should be read-only and load the operating system; therefore, surviving reboots to the same state until the media is replaced 2) should be inexpensive 3) hopefully small but more than two Ethernet ports if necessary cd-rom is familiar yet some folks are using usb sticks and perhaps even other media that I have not considered yet. This is the only list that I am subscribed to at the moment. Thanks to anyone that replies. Darrel
