It would seem that I am not nearly as clear on how to set up
my firewall as I thought.  I am trying to get all the
planning done before purchasing GnatBox, but I have hit a
wall, because in the past the only firewalling I have used
is packet filters on the router.  So, here is my scenario,
and if anyone would like to comment on it, I would
appreciate it.

Just to be simple about it, I will give the info my ISP gave
me, with IPs changed around a bit.

Useable address range: 210.240.164.130-158
Subnet mask: 255.255.255.224
Gateway: 210.240.164.129

For my workstations, we use a proxy server.  For the
servers, it is quite clear to me how to "put 'em on the
internet", but what I want to do is put them behind the
GnatBox.  I guess I do not grok how to do this while
preserving the "real" IP addresses for my servers.  Do I
further divide the subnet?  If I put them on the DMZ, they
wind up needing a different address depending on whether you
are accessing them from the External network or the
Protected network.

Maybe I just have not had enough coffee yet, but I am really
confused.  Someone care to help?
BTW, all of the important servers are Unix of some variety,
so we have all the configurability there we need.  I also
operate my own DNS and have complete control of the entire
domain in case I have to play wierd name resolution games...

Thanks in advance,
-Bryan
