Greetings all.

If anyone has any recommendations for a firewall  to accomplish the
following, please let me know.  Also, is this technically feasable?

Here is the scenario:
Servers A, B, C, D

Each server is on a seperate network.

Servers A, B, C need to pass data to server D, and vice-versa.

Networks A, B, C must not be able to talk to each other.

Diagram:
                     A 
                      |
                      |
   D----------FW-------B
                     |
                     |
                    C

All network topology is 10Mbps Ethernet.  There won't be a tremendous amount
of traffic going through the firewall, mostly just TCP.

Thanks in advance,
Irwin Lazar
