You can contact directly via mail a WSUS specialist that may have current IP addresses - jchornbe (a)microsoft dot com or at chip.hornbeck (a) outlook dot com. Or at least he will redirect you to another WSUS specialist. Ports are standard ones 80 for http and 443 for https. Your task is not very uncommon. Feb 27, 2014 Trying to figure out the registry keys to modify, in order to point Windows 7 client computers to a WSUS server on our LAN. Several online articles specify the two following reg. Point Windows 7 Regedit to WSUS Server - Spiceworks. The HTTP(S) URL of the server to which reporting information is sent for client computers that use the WSUS server that is configured by the WUServer key. This policy is paired with WUServer, and both keys must be set to the same value to be valid.

For security purposes, the IP address for the Windows Update web site constantly changes and it is not a fixed address. Also, there is no official publication of the IP addresses. We normally advise against defining IP addresses on the firewall for this purpose. Instead, we suggest either allowing all outbound connections to http & https ports or defining the DNS addresses as permitted destinations for traffic via the firewall.
For up-to-date information about the IP's being used by Windows Update, use the DNS system, as this is the only reliable up to date source of information. If you use DNS, make sure the following destination hosts are specified:
http://windowsupdate.microsoft.com
http://*.windowsupdate.microsoft.com
https://*.windowsupdate.microsoft.com
http://*.update.microsoft.com
https://*.update.microsoft.com
http://*.windowsupdate.com
