We used a GnatBox here for a while to keep our business office server
from seeing our library server as well as give the BO folks a bit of
internet access. (The two Netware servers in question were set up in the
same tree, and we didn't want to combine 'em)
The GnatBox was terrific! BTW, it runs FreeBSD. Since we had few actual
users behind the firewall, we set it up on an old '486 with 16 MB RAM
and a bad HD controller--it runs from one floppy! The admin program
permits a pretty complex range of options, so you should have no
troubles setting up the Exchange server behind it. Len is correct, it
should be on the DMZ, which would be a third NIC for the box. Should be
just fine. We didn't _notice_ any slowdowns with 6 users and 10Mbps
connections to the rest of the network. We were pleased with the system.
