Do I need a sepaprate box for the ISA Server or can it sit on the same box as any of the other two?

Thanks

You need to invest in a real firewall like ISA server that way you do
what you are asking without worrying about port 80 being signed to one
machine.

I currently run a web server on a separate box and Exchange on another
which my users can access their web sites and emails from, both are
running on port 80, however my ISA server knows what is coming in for
web and what is coming in for OWA and thus points the connections to the
right server.

Using your everyday Linksys type router will not work for you. If you
can't afford to invest in a proper firewall then I suggest you run your
web sites from your Exchange Server and dump the Apache box.

Hello all,

I have a peculiar problem. I have two win2k3 Enterprise on my network.
Apache webserver is sitting on one, and Exchange 2003 Enterprise is
sitting
on the other.

The Apache Server came first and so the router has been used to map Port
80
to the Apache Server. Now with Exchange installed, the question are two
folds:

1. Exchange was installed and Microsoft Certificate Authority was
generated
and used. So SSL is on. Based on this, if the users are willing, can
they
access OWA through HTTPS and not bother with HTTP since Port 80 is in
use by
the Apache Server. That way, the router can open Port 25, 110, and 443
to
the Exchnage server? The main way of connecting to this server is mostly

through OWA.

2. I have forgotten whose address I put in Forwarders in my DNS entry
(Would
that be my WAN IP?), and whether I need to include MX record in my
forward
lookup zone.

Thank you all in advance.

Ola
