then put a firewall on the edge of your network, you don't need GPO to do this.

Group Policy isn't the right tool for this. Use your firewall for this.

Can I use firewall rules in one OU only? – or can we use Microsoft AntiVirus to block WebSite Access?

In general you will find that people use a completely different approach to restrict internet access, as AFAIK even if GPO's with allow/block lists can be set up, those will then only work for specific applications (the GPO for Internet Explorer won't work for Chrome, powershell code, or Firefox for example) and such GPO's are therefore both easily circumvented and a PITA to maintain.

The usual approach is:

  • install a proxy server (with authentication and here you will enforce your access policies)
  • block all direct internet access from desktops/servers at the network level
  • only permit internet access through the proxy server
  • use a GPO to set the proxy in network settings

https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/windows-firewall-with-advanced-security-design-guide suggests that Windows Defender can *"control what network traffic the device is allowed to send to the network"* and has GPO support. No idea if that is fit for purpose, you'd have to experiment.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
