vSphere Update Manager Network Connections

Recently I was struggling getting vSphere Update Manager to work properly across firewalls. Information for the required firewall ports that need to be opened can be obtained from the following VMware KB articles:

http://kb.vmware.com/kb/1004543
http://kb.vmware.com/kb/1012382

During troubleshooting, some information got me confused and as the saying goes, “a picture is worth a thousand words.”, I decided to craft a picture from all this information.

vCenter Update Manager
