Reverse Proxy setup for Mobility HTTP 80 configuration not working

http://technet.microsoft.com/en-us/library/hh690011(v=ocs.14).aspx

I'm trying to use the Port 80 ->8080 setup to avoid putting lyncdiscover.sipdomain.com for every additional sip domain that we want to include.

I have followed the instructions per the above link, yet when I try to log in with a user with one of those additional SIP's, I cannot log in to a mobile device.

For example,

our main sip is "contoso.com", so abby@contoso.com can log into her mobile device.

but user bill@fabrikam.com cannot log in via mobile device.

Is there anything else that needs to be done to ensure that bill@fabrikam.com can login via a mobile device?

Auto login?

Here is the testexchangeconnectivity.com

When I run the Lync Mobile Test, I get this, almost like the http rule is useless, still requiring the need for the additional lyncdiscover.sipdomain.com .

bill@fabrikam.com
