Feb 22, 2021 macOS Big Sur 11.0.1 refuses to load Tunnelblick's existing, notarized system extensions unless SIP is disabled. It isn't known if this behavior will be present in future versions of Big Sur; 11.1.0 does not require SIP to be disabled. FortiClient VPN Works in both Big Sur and in guest OS Linux/Windows over NAT. OpenVPN (Tunnelblick connections) works in Big Sur but not in Linux/Windows over NAT. All internet traffic to virtual machines also stopps as soon as I connect VPN. Disconnecting VPN returns internet access. Cisco AnyConnect, same as OpenVPN.

When running on macOS Big Sur 11.0.1 or later, Tunnelblick forces the settings on Tunnelblick’s “Advanced” settings window to “never load” system extensions. (The developers plan to release a version of Tunnelblick which will be “smarter” about this.)
