My school has already deployed a pure-IPv6 network with NAT-PT. But there are massive applications cannot support IPv6, so these applications cannot work at all. Now I *DO NOT* wanna build a dual-stack network, because if I build a dual-stack network, IPv6 will have no users, all users will use IPv4 to communicate with the websites which in IPv4 network. So I wanna build a tunnel, the start-point is client, the end-point is a special dual-stack machine. Also, a sock5 proxy is all right. Could you tell me how to do this? thx! -------------- Bear 2010-06-16
