What is fbL2tpTunnelsFree?

This counts how many L2TP tunnel slots on the Firebrick are currently in the FREE (unused, available) state. An admin watches this alongside fbL2tpTunnelsLive to gauge how much tunnel capacity remains for new connections. For example, fbL2tpTunnelsFree dropping toward 0 while fbL2tpTunnelsLive climbs signals the device is approaching its configured tunnel capacity.
