    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 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 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.

  2. 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?

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