networking / firewall nightmare

yes i know my post count is at 1... i can't remember the login for my main account and i dont have access to my email right now to retrieve it... so:

ill start w/ the graphics, stand back they are cutting edge:

graphic of whats going on here

ok so here is the jist. this moves from left to right.

i have an internet connection coming in, plugged into a box running win2k and some ftp software (A) and two nics

the 2nd nic then plugs into the WAN side of a netgear fvs318 firewallnetgear fvs318 firewall (B).

from the firewall, the LAN ports connect to an internal LAN with it's own IP setup and domain (C).

What i need it to do is the following, which i can't so far manage.

traffic comes in from the internet to A and can only access (in theroy) the ftp software via an ftp client (that part is the easy part). with the firewall B next in line, i need to prevent them (or a hacker) from getting anywhere past that firewall B onto the local network C

with me so far, that part is pretty straight foward.

what gets complicated, is that i want to be able to acess shared directories on the win2k box A from the lan C from network neighborhood on any computer on the lan, which is on the domain.

i need the firewall B to only block from left to right as far as the firewall

if it makes it easier, think of the lan C as a computer with it's own access to the internet / intranet, or as a switch... not sure if that complicates things or not.
 
Instead of running dual NAT, why don't u setup a firewall that supports more than one subnet. It would allow you to branch your ftp server off on it's own subnet.
