I think Alistair is right.

You should separate the two networks with a hardware-router/switch.
Behind the switch you can place your firewall for securing the inner network.
The CPU depend on the traffic getting through. A 200MHz IMHO should be
the bottom level.
Take a cheap Pentium II or III with 400/500MHz and at least 256MB RAM.
