Re: IPv6in4 tunnel with only one /64 prefix
Following-up on myself... Of course Steve's suggestion was not what I wanted to hear, as I wanted to do stuff myself :) The take-away is that my plan works. I have a full write up in French at http://tar-jx.bz/notes/tunnels-ipv6.html ; I can translate into English if people are interested. Basically, you need to tell the external interface that it is not in a /64 addres, then you can add the routes you need. There is nothing special to do on the router at the other end of the tunnel, except turning on the DHCPv6 server. I did have to setup an NDP proxy, the (quite trivial) code is at https://gitweb.fperrin.net/?p=ndp6.git. I did hit a bug in ISC dhclient. There is a fix in the Debian bug tracker http://bugs.debian.org/684009 (a similar fix in Network Manager for desktop systems already made itinto their git). Le mercredi 7 à 22:21, Frédéric Perrin a écrit : Hello list, I have a FreeBSD server with native IPv6 connectivity. At home, my ISP provides me with only IPv4 connectivity. In order to get IPv6 to the home, I had the idea of creating a 6in4 tunnel between my home gateway and my FreeBSD server. The part about creating the tunnel, routing between the home and the server works using private addresses (fc00::/8 over gif0). However, I only have one global /64 on the FreeBSD box. What can I do? I have the idea of subnetting the /64 into e.g. /80, route a couple of /80s through gif to the home and use another /80 for the FreeBSD server. However, as the router into which my FreeBSD server is connected will expect the entire /64 to be directly connected, I will have to setup some kind of NDP proxy for the /80 to the home. I will also lose autoconf, but I can live with that.

Why not just get a tunnel from one of the tunnel brokers, at least he.net and gogo6.com are still running free tunnels. -- Steve O'Hara-Smith at...@sohara.org ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
