basic firewall question

[Ognen Duzlevski <maketo@sdf.lonestar.org>]

Hi,

we have several boxes with unique public IP addresses which are part of a 
big .edu namespace. I would like to put these
machines behind one single firewall and still keep their names. Is it 
possible to have all names point to the firewall
machine and then have the firewall direct the specific request to a 
specific box behind it?

So, if F is firewall.x.edu and I have A.x.edu, B.x.edu and C.x.edu I want 
to have A, B and C behind F. A, B and C
should now point to F and F will direct all outside requests to A, B or C 
based on the name.

Thanks,
Ognen
