Quick Menu Button to Cause Firewall to Block All Traffic

If something indicates your system is under attack, and the attacker is possibly getting through the Norton Firewall, it would be very nice to have a Quick Menu Button to Manually Cause the Norton Firewall to Block All Traffic.  This would be a fast check on the potential problem, and faster than going to the router and unplugging it.  There should be some indicator, bubble, window, or color change to show that all traffic is blocked manually.  I am using the latest version of Norton 360 on Windows 10.
