I have been struggling with this issue for too long and guess I have to admit : I need assistance ! :-P
I need to set-up OWA for remote users to acces their corporate mail.
It works just fine ovet regular HTTP, but after some reading I discovered that this is actualls quite bad (no encryption...)
So I decided to switch to HTTPS, and issued my own certificate as per described here: http://www.msexchange.org/tutorials/Securing-Exchange-Server-2003-Outlook-Web-Access-Chapter5.html
It is working very fine from inside the network (LAN), both HTTP and HTTPS.
But when tested from outside our FW, only HTTP works.
- When reaching HTTPS URL, IE gives a "Page cannot be displayed"
- When tested with Firefox, it says that the connection attmp has been dropped.
I have a linux box sitting outside our LAN "just in case", so the first thin I did was test the opened port on the FW for my IP:
80/tcp open http
135/tcp open msrpc
443/tcp open https
Looks quite ok for me.
Then I thought it could be a problem with the certificate, so I ran (from outside box) a openssl to see what happens.
openssl s_client -bugs -connect MY.IP.ADD.RESS:443
3827:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188:
and this is where I stand...
Any hint ?!? Seems to be an SSL problem, and I really am a newbie for that...
