Or > must one tunnel at this point? I love either-or questions like this. The answer is... Yes! Yes, you can get routable IPv6 addresses. But, you have to tunnel to get to your tunnel broker. Tunneling is nothing more than a transport encapsulation. Nothing magic there. Just like ppp is a tunneling encapsulation. You're just connection your gateway up to the broker's gateway and the transport protocol happens to be IPv4, instead of PPP or PPPOE or ATM or Ethernet. Same principle applies. Your addresses are all routable (and the routing is independent of IPv4 - I love it when someone tries to claim "but IPv4 is doing the routing") and you've merely connect up your gateways. Oh... And there are times when setting up my internal tunnels between several SLA's that I use PPP over stunnel rather than SIT. The issue of gateway connecting transports is completely orthogonal to the issue of IPv6 routing and addressing. Mike -- Michael H.
