Outlook Web Access - Disable Port 80

Posted on 2011-10-20

We are using Exchange 2003 and have OWA setup. The URL responds via port 80 and 443 for logins. I want to disable port 80. Port 443 is setup with a certificate. I checked in IIS Manager, but can't delete port 80 from the box to leave it blank. It wants a port there.

What should I do:

1) On my firewall forward port 80 to 443?
2) Or something else?

    You could bind port 80 to the internal IP of your server, and therefore it won't accept connections from external clients on this port.

    How do you do that in Windows? I'm not understanding clearly.

    I'll use the internal firewall to block port 80. Thanks.

    Thank you for awarding the points.  In answer to your question, within IIS on the website properties is where you would be trying to delete the port number.

    If you click on the advanced button to the right of this you will open the advanced web site id screen.  From here select the entry with Port 80 from the top box - it is likely to be the only one - and click edit.

    In this screen you can select from a list of IP addresses.  Assuming this server has a public IP and a local IP you should select the local IP address from this list.

    This would allow requests from your LAN to port 80, but not from the external interface.
