I need to find a firewall that will give me 1 LAN port, and 5-7 DMZ ports.

I have a requirement to replace some FreeBSD systems that are used to run some testing equipment. It is essential that the DMZ ports cannot communicate with each other, but the LAN port can communicate with everyone. That way a user on the LAN can connect to the test systems, but the test systems are isolated entirely and cannot interfere with each other.

One of the DMZ's will be connected to a VMWare ESXi server, one to a standard server, and the rest to various types of equipment.

The lan port will be connected to the corporate LAN switch.

Sorry if i am a little vague, I am just trying to work all this out myself! Currently we have a FreeBSD configured, but the quad port NIC's are pretty expensive, and the PC itself is old, so i would prefer to replace it with a dedicate piece of kit which can do the same job, but more reliably! These test rigs are used all over the place, and get moved quite often, so i am aiming for Cisco kit for ease of configuration and reliability of the hardware itself.

Thanks
