They are 3 separate class c's, from 3 separate providers. So they are

We have 3 firewalls currently; each covering one ip range/connection
out. Each ip range has been aliased onto each firewall, so they know
all the routes between each other. There are 3 ip addresses per inside
interface of each firewall. I am trying to keep the internal traffic
from getting as far as the firewalls. Right now, I am only concerned
with routing away from two of these firewalls.

These are 3 public ranges and we are unable to switch to NAT at this
time. One range is specifically for hosting customers, one range is
primarily for workstations and internal servers, and one is a hodgepodge
of both. We DO want each of these networks to get to each other, that
is the exact thing I am trying to accomplish. I do not need to keep
them separate from each other. I want the traffic to pass between all
three networks without hitting our existing firewalls. The monowall is
going to be more of a router than a firewall.
