FIX: You cannot apply a UAG SP1 Update 1 array configuration that contains an HTTP to HTTPS redirection trunk

Consider the following scenario:

• You create a Microsoft Forefront Unified Access Gateway (UAG) 2010 Service Pack 1 (SP1) array.
• You enable integrated network load balancing.
• You install UAG 2010 SP1 Update 1.
• You create an HTTP redirect trunk to an HTTPS trunk in the array.
• You try to apply the configuration.

In this scenario, you may receive an error message that resembles the following:

This issue occurs because the external port number of the trunk is automatically set to 0. Because 0 is an invalid port number, the array configuration cannot be applied.

To resolve this issue, install the rollup package that is described in the following Microsoft Knowledge Base article:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

When UAG SP1 Update 1 is in array mode, the trunk port number is automatically set to 0 regardless of the port number that is configured in the management console. Therefore, the array configuration cannot be applied, and you receive the error message that is mentioned in the "Symptoms" section.
