Exchange 2010 Outlook Web Access
OWA works from inside with the below Internal address but not from the outside. Do I need to enable port 587 for Exchange Services on my Sonicwall?

I am experiencing intermittent Internet . Even while typing on the iPod it went out again. I am fairly certain those ports are open but will have to check when internet is up again.
To use OWA you need to forward the following ports on your firewall to your exchange server and then test to confirm that they're open.
port 25 (SMTP) and port 80, 443 (SSL)
To test them, use a command prompt from a computer that is external to your network and type the following command: ie: telnet myserver.mydomain.com 80 and you should get a connection on this port, if it is a black screen, that doesn't matter, as long as there is a connection, but if it times out it means the port is not being forwarded properly to your exchange server. Do this for each port, to ensure that the ports are forwarding properly.

Email does flow freely. Port 25 is open, verified with telnet. Port 80 and 443 do not connect. I am checking the Sonicwall. Be right back.

NOTE: Email to the Exchange Server - not OWA.

https://mail.[domain].org/owa produces "Explorer cannot display the webpage." Not the page that has the red shield on it saying the certificate cannot be validated...proceed with caution to the website.

GOT IT: The Exchange Service in the Sonicwall did NOT have HTTP (Port 80) or HTTPS (Port 443) assigned to it. Once assigned, Bingo!
Thanks.
Thanks.
Sorry but why do you need port 25 opened to access Exchange via OWA?
