Error Testing Lync Connectivity

I am in the process of launching Lync 2010.  Everythign seems to be working alright.  I can connect up from the outside with my laptop with no problems.  I just have one issue.  I obviously want to launch the system with no errors.  I am not sure if this is even anything to worry about as I said I can remotely access the system without any problems.

When I run the test on testexchangeconnectivity.com for the Lync remote configuration I get the following error.  Does anyone know what causes these errors.

Testing remote connectivity for user tuserit@domain.com to the Microsoft Lync server.
       Specified remote connectivity test(s) to Microsoft Lync server failed. See details       below for specific failure reasons.
        Tell me more about this issue and how to resolve it

The tool must be able to access port 25, 80, and 443

I am guessing you are running on server 2008, here is how to check the ports

Of course, if there is any firewall in between, you need to check that as well.
