SBS 2011 Remote Web Access Connection Fails

I have installed SBS 2011.  I can access RWA within the LAN when I enter http://remote.domainname.com or https://remote.domainname.com in browsers on various PCs.  When I try to access remotely from a home client PC (Vista & Win7) I cannot connect. I get: "Internet Explorer cannot display the webpage."

Here is what I have done so far:

IE 8:
Ran IE diagnostics.  No problems detected.
Added site to  trusted locations
checked security settings in adanced tab for SSL & TLS
I can ping the domainname. It responds with correct IP address and replies.

Router:
Checked that the ports are open.  They are and were set by UPnP with SBS.
Tested that the ports are open at No-ip.  They are open.
Ping domainname.  I get correct IP address and replies.

Server:
Ran Fix my network.  It found no errors.
Checked the firewall settings.  They are okay.
Internet connection is okay
domain name is okay.
Self issued certificate is okay.

Any ideas? Your wisdom is greatly appreciated.

Thanks.

You are having a third party SSL certificate installed or Self Signed? If Self Signed, then you need to install the certificate on the local desktop for the RWA to function.

Go to http://mxtoolbox.com/PortScan.aspx perfom port scan see whether all the required ports are open.

Hope this helps,

Shreedhar,

It is a Self Signed certificate.  I installed it on the remote client and it still doesn't work.  I get the same result.

Checked the ports with your link and the ports are open.

I suspect that the certificate is not installed properly on the desktop.

I copied the certificate intallation package to my remote desktop.
Extracted all files.
Ran installation app.
Opened IE.
Opened Tools -> Internet Options -> Content -> Certificates -> Trusted Root Certification Authorities.
Scrolled down the list and my certificate is listed.

What else can I check?

The problem was a combination of  certificate & DNS issues.

I got a GoDaddy Certificate.  The self signed didn't work well for us.  Don't remember the DNS issue.
