There are probably many ways to do this, here is one that I
know will work:
use a Sun box running Solaris, with a Quad-Ethernet Card.
Install a commercial firewall product. Plug in each server
into its own ethernet port on the Quad-ethernet card.
Configure the firewall product to allow traffic between the
servers as you described. If you were to use CheckPoint's
Firewall-1, assuming you had your config info all worked out,
and the security policy thought out. You could have it done
in an hour.
