OWA

[Guest]

I am trying to allow my users to access their mailboxes from any location.
Our exchange server is behind a firewall perfroming NAT. The gateway has a
dynamic IP, and we connect to the internet through a cable company. How can I
do this with OWA? I don't know what server to tell it to look for because we
don't host our website and, as I said before, have our connection through the
cable company.

I am trying to allow my users to access their mailboxes from any
location. Our exchange server is behind a firewall perfroming NAT.
The gateway has a dynamic IP, and we connect to the internet through
a cable company. How can I do this with OWA? I don't know what server
to tell it to look for because we don't host our website and, as I
said before, have our connection through the cable company.

You can use the public IP address. But to make things easier with dynamic
IPs, try using something like the free dynamic DNS service at www.dyndns.org
& download DirectUpdate to update youraccount.dyndns.org (or whatever you
choose as the host/domain) - then open up port 80 inbound/forward it to your
server's LAN IP and use

http://youraccount.dyndns.org/exchange

*Much* better still, don't open port 80 - use SSL (you can create your own
cert by installing Certificate Services on the server) and open up port 443
instead, and use https://... better from a security standpoint.

Note - in the future, best to post OWA questions to m.p.exchange.clients -
OWA is part of Exchange, not Outlook.

I am trying to enable my users to access OWA from the internet. I have it
working perfectly on the intranet, but when I try to access it from the
internet, I get an error saying that I am not authorized to view the page. No
login dialog pops up. I am using https:// to connect and have forwarded port
443 to my server (behind a router using NAT). The only thing I can think of
is that the software firewall installed with Win Server 2k3 must be blocking
the connection, but I can't figure out how to unblock it. Please help!
