   Pretty close.  The IPv4 tunnel is actually carried on IPv4 via the router's   
   NAT.  I got the tunnel, because I wanted multiple public IPv4 addresses.   
      
    MvV> So when that tunnel folds, you no longer have IPv4 incoming on the

   Correct.

    MvV> Right.

    MvV> s/IPv6/IPv4/ ?   
      
   Yep, oops typo lol.

   It's dual stack, it's just because of how the actual IPs for the BBSs are   
   obtained (as additional IPs) there is this quirk.
