WSUS

Hola,
sacado del manual de configuracion de WSUS de Microsoft, Corto y pego:
Configure the Firewall Between the WSUS Server and the Internet
If there is a corporate firewall between WSUS and the Internet, you might
need to configure the firewall to ensure that WSUS can obtain updates.

To configure your firewall

· If there is a corporate firewall between WSUS and the Internet,
you might need to configure that firewall to ensure that WSUS can obtain
updates. To obtain updates from Microsoft Update, the WSUS server uses port
80 for HTTP protocol and port 443 for HTTPS protocol. This is not
configurable.

· If your organization does not allow those ports and protocols
open to all addresses, you can restrict access to only the following domains
so that WSUS and Automatic Updates can communicate with Microsoft Update:

· http://windowsupdate.microsoft.com

· http://*.windowsupdate.microsoft.com

· https://*.windowsupdate.microsoft.com

· http://*.update.microsoft.com

· https://*.update.microsoft.com

· http://*.windowsupdate.com

· http://download.windowsupdate.com

· http://download.microsoft.com

· http://*.download.windowsupdate.com

· http://wustat.windows.com

· http://ntservicepack.microsoft.com

Note:

The steps for configuring the firewall above are meant for a corporate
firewall positioned between WSUS and the Internet. Because WSUS initiates
all its network traffic, there is no need to configure Windows Firewall on
the WSUS server.

Although the connection between Microsoft Update and WSUS requires
ports 80 and 443 to be open, you can configure multiple WSUS servers to
synchronize with a custom port.
