The software updates feature in Configuration Manager 2007 requires different ports to be available for communication between clients, site systems, and site servers, and for the software updates process to function properly. This topic provides three typical scenarios, each of which make the following assumptions:

• The site systems for both sites are configured to use the default Web site. Therefore, depending on the scenario, communication from the distribution point and management point site systems to clients is configured for HTTP port 80 or HTTPS port 443.
  
  
• Windows Server Update Services (WSUS) on both active software update points is configured to use the custom WSUS Web site. Therefore, depending on the scenario, communication between the site server and WSUS running on the active software update point, as well as from client computers to WSUS running on the active software update point, is configured for HTTP port 8530 or HTTPS port 8531, by default.
  
  

The following sections describe the different scenarios and provide information about the ports used by software updates in each scenario:

• Mixed Mode Site Without SSL on WSUS
  
  
• Mixed Mode Site With SSL on WSUS
  
  
• Native Mode Site With SSL on WSUS
  
  

Mixed Mode Site Without SSL on WSUS

The following diagram provides information about the ports used when the Configuration Manager site is configured for mixed mode and WSUS is not configured to use Secure Sockets Layer (SSL).

Mixed Mode Site with SSL on WSUS

The following diagram provides information about the ports used when the Configuration Manager site is configured for mixed mode and WSUS is configured to use SSL.

Native Mode Site with SSL on WSUS

The following diagram provides information about the ports used when the Configuration Manager site is configured for native mode and WSUS is configured to use SSL.
