I think this may not fit well to hackers, so I added reply-to: freebsd-net into headers. >> One thing we don't implement intentionally is automatic tunnelling >> (packets to ::10.1.1.1 automatically tunnelled over IPv6-over-IPv4 >> tunnel to 10.1.1.1). >Hmm..what does happen when I have a IPV6/V4 host that has an IPV6 >native address (so no V4 compatible address) that wants to communicate >to an IPv4 host? Do I need to set up IPV4 specific routes to >a dual stack machine that does the tunneling for me? Your story has nothing to do with auto tunnel. Automatic tunnel (::10.1.1.1) is only for communication between two IPv4/v6 dual stack hosts. For a IPv6-only host (or IPv4/v6 dual stack host without IPv4 address) to communicate with IPv4 host, you need to have IPv6-to-IPv4 translator (TCP relay server like socks or KAME FAITH, or web proxy) between two. There's no magical way. itojun To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
