you need to free up port 443 (requires https)

Hello Patchemus,

irwinpks might be right. If you set up owa to use secure socket layer with a certificate, you will need to type in https:\\whatever.whatever. Note the s in https. This will need 443 to be open.

If you did not set up secure socket layer, you might need to look in a different direction. Can you be more specific about the error ? what is the error number?

Is the server conencted to the internet through a dedicated NIC? If so you also have to allow access to the different IIE services for this specific NIC.

Have a network address translation (NAT) rule on your firewall which redirects traffic from the external address associated with the domain.com address and the internal address of the firewall?

A port address translation for just port 443 will also be sufficient.

Saineolai is right.  Unless the box running OWA has an external IP address, you will need to forward the appropriate port (either 80 or 443 depending on if you are using SSL) from the router to the server.  If you simply open port a port, it doesn't know where it should go.

It's a good idea to use SSL to secure the page if you are opening it up to the world.  Since you have SBS 2003, you are running IIS 6.0 and can use selfssl.  Selfssl is provided by MSFT as a way to secure your site without buying a certificate.  Selfssl is part of the IIS 6.0 resource kit and you can download it from http://www.microsoft.com/downloads/details.aspx?FamilyID=56fc92ee-a71a-4c73-b628-ade629c89499&DisplayLang=en.

@Saineolai & bdsmithback...Patchemus already mentioned that port 80 was not blocked in his original question, that's why I suggested only port 443 in the first comment

Sorry irwinpks - I don't think I was very clear in my comment.  It's not a question of being blocked.  It's a question of being forwarded.  If there is a router on 192.168.0.1 and a server on 192.168.0.10, unblocking port 80 on 192.168.0.1 doesn't help because it doesn't know that the traffic on port 80 should be redirected to 192.168.0.10.  What we will see is that when you go to port 80 from the external address, it will be trying to open port 80 on the router and not the server.  192.168.0.1 needs to forward port 80 or 443 to 192.168.0.10.  I should have clarified this.  The other possibility is that the server has an external IP address and is not behind a firewall.  If this is the case, irwinpks - you are correct.  Open up 443 on that box to see if IIS is set for SSL.  Patchemus - what is the current network setup? Is the box in question behind a firewall or does it have an external address?  Sorry for the confusion - I was making an assumption that I shouldn't have jumped to. :)
