<div class="content wysiwyg-content">
Here is my problem:<br />
<br />
I have one public IP address.<br />
1 TS Web Access + TS Gateway (Windows 2008)<br />
1 Exchange Server with OWA enabled (Windows 2008 R2)<br />
1 Forefront TMG 2010 (Windows 2008 R2)<br />
<br />
<br />
Internally everything works fine but externally:<br />
<br />
My OWA is working without problem because my listener in TMG is configured to use FBA authentication but TS Web Access + TS Gateway are not working because they need that the listener to be configured with &quot;No Authentication&quot;.<br />
<br />
I can't configure two different listeners for port 443, it must only exists one listener for the same port.<br />
<br />
How can I resolve this issue?

Here is my problem:

I have one public IP address.
1 TS Web Access + TS Gateway (Windows 2008)
1 Exchange Server with OWA enabled (Windows 2008 R2)
1 Forefront TMG 2010 (Windows 2008 R2)


Internally everything works fine but externally:

My OWA is working without problem because my listener in TMG is configured to use FBA authentication but TS Web Access + TS Gateway are not working because they need that the listener to be configured with "No Authentication".

I can't configure two different listeners for port 443, it must only exists one listener for the same port.

How can I resolve this issue?
