Why cannot Windows 10 Update connect to its update servers even though there is a working internet connectivity?
About my setup
- running Windows 10 on a PC behind a dedicated firewall (pfsense 2.2.5)
- there is internet connectivity, port 80 / 443 works fine for anything else
- connecting the Windows 10 PC directly to my IPS's modem allows to update Windows 10 => suggests that the firewall is causing the problem
Already checked
- pfsense forum with the result that Windows 10 update should work without any hick-ups (not running any proxy)
- found and tried the resolutions mentioned in the MS Support article Can't download updates from Windows Update from behind a firewall or proxy server
Still, Windows 10 (version 1511) cannot update itself when I run it behind my firewall.
Any other suggestions/ideas?

Hmm... Maybe I need to try out that firewall... – Andrew – 2018-08-11T22:12:34.583
