Does any vendor make ethernet bridges that are solid state and about the size of a cigarette pack? Ideally I would like to find a vendor that offers these as plug in modules into a single rack mounted frame, so I could get a lot of them in a tight space.
I want to use one of these in front of each segment on a 12 segment firewall, to filter any source IPs on the segment or filter by Mac address. The spoof detection on my firewall is harder to use than it should be and introduces reliability issues I don't want to deal with.
I know that Allied Telesyn, Canary, and others make small copper to fibre converters that are small and fit into rackmountable enclosures. I am hoping that maybe one of them had the foresight to add in some ethernet bridging capabilities to those.
