You know what it's like when you need a product that you remember seeing a few years ago. You didn't need it then, but you need it now, and you can't find any information about it anywhere!
I'm looking for a manual switchbox - similar in principal to a printer switch - that can switch a network node between two different Ethernet LANs.
In other words, the client PC has one NIC connected to the switchbox, but two LANs ("A" and "B") connected to the switchbox. The client can either be connected to LAN "A" or LAN "B", but not both simultaneously.
I know these are used by some of the more secure government departments, but any idea who manufactures them?
BTW, intelligence such as connection spoofing isn't necessary - if the users have to reboot and login again, so be it.
