Block Internet Access while Allowing Local Area Network (LAN) Access
You can configure the firewall to block internet access while allowing connections to an internal network (intranet or LAN).
Example scenarios:
- In your network at home, you want your child's computer to connect to other computers at home but disable their internet access for safety reasons
- In a company network, you want employee computers to connect to your network but disable internet access for bandwidth reasons
Create the global rules
