SBS 2003/ISA firewall/hardware firewall/OWA/second web server

Hi All,

I have an existing SBS (2003 premium) installation and I want to wipe the
server (after backing up all the data, settings etc!) and start from fresh
for a variety of reasons. I just want to run the config through here so
anyone who has done a similar install can comment.

Is it possible to install SBS as follows:
1) Have a hardware firewall routing out any really nasty attacks
2) Have SBS 2003 with ISA presented as the software firewall.
3) Any requests for www.domname.co.uk/exchange are handled by OWA on the SBS
server. I guess that the supporting subdirs (public and exchweb?) are also
handled on this server.
4) Unhandled web requests (such as www.domname.co.uk) are handled by another
server in the SBS domain.

As you can see I essentially want SBS to have OWA access from externally
(and internally if wanted) but also retain access to our websites located on
a second server.

At the moment we have a Cisco firewall that I can't configure myself that is
pointing all port 80 requests to the webserver and all port 25 requests to
the SBS server so obviously we can't currently have external OWA access
(unless a VPN is opened first).

I've checked out a whole load of websites and for the life of me cannot find
an example of this - I did managed to find some about 6 months back but they
don't appear to be still around and I can't remeber what the conclusions were.

Any help/advise/website links would be very appreciated.

Regards,

Jon.

 

if you configure OWA for https with SSL which uses Port 443 then you could
forward that to your SBS server and get OWA
I'm going to refrain from getting on my soapbox about running externally
available websites inside the domain.

 

True although with the first option the internal websites couldn't then have
SSL from outside.

Good point - maybe I should really look at doing it properly. Any good
websites with info on OWA/ISA running with an domain-external site?

Regards,

Jon

Thanks for that Marina although I couldn't find details about how it's setup
with ISA, etc.
