linux odd firewall setup help.

Hi,
At my work, we have a very unstable firewall running on windows. (raptor).
Well, the boss is sick of it flaking out every half hour or so. So, they
asked me to setup a linux firewall. Ok, no problem. However, there is one
catch, the raptor firewall does something strange. Here is the problem:
(first here is the setup).
development servers are on the 192.168.xxx.xxx network.
developer workstations are on the 10.xxx.xxx.xxx network.
firewall on 192.168.xxx.2 and 10.xxx.xxx.33 (which is the gateway to the
development network.)
The development servers use to be on the 10.xxx.xxx.xxx network, previously
but then security demanded they be behind a firewall, so they got moved
behind a firewall and put on the 192.168.xxx.xxx network. All fine up to
here. However, the developers set things up in such a way that they still
need to use the 10.xxx.xxx.xxx ip addresses of the development servers in
order to access them. Currently the raptor firewall just forwards any
requests for those machines old 10.xxx.xxx.xxx ip addresses to the
corresponding 192.168.xxx.xxx addresses. I'm not sure if it's doing that via
proxy arp bridging or what.
What do I need to do to set this same thing up on linux? I've looked at proxy
arp bridging, but I'm not sure if this is what I need, or if it will work.
Thanks,
Sheldon.
