Being that you do cover such a wide range of scenarios on the site and
in your books I think it would be greatly appreciated by those of us
that use this setup to have an aritcle or two dedicated to this setup.
What you'd be doing is expanding on the TZO packet filters article
that you have listed on the site and preceeding the articles you have
on publishing the OWA. So if you have the time by all means, hook us
up. :-)

I went and deleted the listener I had for the internal IP and
configured the web server listener as follows:
1. Checked "Use a server certificate to authenticate to web clients"
box and selected the FQDN the users will use to connect to the OWA
site.
2. Checked the "Bsic with this domain" box and selected my domain.
3. Made sure the "Enable SSL listeners" box was checked.
4. Published ports 25 & 80 on the linksys router/NAT device.
I can access the OWA site internally but not externally. What steps am
I missing?
TIA
