Now that the flag includeAllNetworks is working as expected (see https://developer.apple.com/forums/thread/722156), I tried to set it and also the ExcludeLocalNetworks flag. As described in the documentation, I'm able to use AirPlay and AirDrop while being connected, but what I was hoping for was to exclude from the tunnel all the LAN traffic, including pings to local hosts, ssh, printer access, etc. Isn't it what ExcludeLocalNetworks should accomplish? If not, how can I exclude LAN traffic from a full tunnel (i.e. not a split tunnel)?
