The release of Whale Communications Intelligent Application Gateway (IAG) 2007 Update 2 for Service Pack 1 includes the following features:

• Smoother integration with Microsoft® Office SharePoint® Server 2007—Integration with Office SharePoint Server 2007 has been improved in order to provide better support and smoother user experience. You can now publish SharePoint Products and Technologies (Windows® SharePoint Services 2007 and Office SharePoint Server 2007) through the IAG portal by using alternate access mapping, which enables mappings between the application's internal URLS and public URLs.
  
• Configuration of a trunk's public host—You can no longer use IP addresses to define a trunk's public host; only host names are supported. In the Configuration console, the trunk's Public Hostname/IP Address box has changed to Public hostname. In addition, host names must contain at least two periods.
  

Update 2 is included in IAG Service Pack 2.
