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. Comments, either on the plan above, or something else I haven't thought of? -- Fred
