I have a Windows 2019 server sitting behind a firewall and an Internet proxy.
What are the network ports and URLs that need to be whitelisted for this server to download Windows patches/updates from the Internet?
I have a Windows 2019 server sitting behind a firewall and an Internet proxy.
What are the network ports and URLs that need to be whitelisted for this server to download Windows patches/updates from the Internet?
Ports: tcp/80 and tcp/443
Urls:
http://windowsupdate.microsoft.com
http://*.windowsupdate.microsoft.com
https://*.windowsupdate.microsoft.com

https://*.update.microsoft.com
http://*.windowsupdate.com

These will work for a proxy server. Not sure about the firewall. Many firewalls allow access to address ranges, not urls. Products such as Office 365 have deterministic IP addresses, although those may still change occasionally.
