I had to do some research on the Internet to figure out how to configure it but once I figured it out everything's been running smoothly since. Now every computer in my house has IPv6 connectivity. I was also able to get my Airport Extreme to connect to the IPv6 Internet with 6to4 without any trouble other than an error message and a yellow blinking light which I think is safe to ignore.Johnhttps://www.blogger.com/profile/04732150297310098451noreply@blogger.comtag:blogger.com,1999:blog-6264947694886887540.post-20328568050961179262011-05-06T13:48:56.825-07:002011-05-06T13:48:56.825-07:00The reason you need

(I have added the '0000' word in the address to emphasise how it is 'subnet 0000' of the 2001:1938:2a9::/48 network.)<br /><br />Also it provides an address for other hosts on your ethernet to target as the router for the default route.<br /><br />This /64 network is actually a subnet of the /48 network you routed with your other command<br /><br />ip -6 route add 2001:1938:2a9::/48 dev lo<br /><br />The /64 route is more specific than the /48 route, so is preferred for packets within 2001:1938:2a9::/64.<br /><br />Packets for any other address in the /48 block will be routed to the loopback interface, which stops them being routed using the default route.Duckbillhttps://www.blogger.com/profile/07997410192039319987noreply@blogger.comtag:blogger.com,1999:blog-6264947694886887540.post-2131368172007750202011-02-27T00:05:49.197-08:002011-02-27T00:05:49.197-08:00Congrats for getting it working.

I've fixed it.<br /><br />I haven't looked into IPv6 routers yet; let me know if you find a good one.Ken Shirriffhttps://www.blogger.com/profile/08097301407311055124noreply@blogger.comtag:blogger.com,1999:blog-6264947694886887540.post-89085392304870638232011-02-26T12:05:37.830-08:002011-02-26T12:05:37.830-08:00Pedantically, it's protocol 41, not port 41, t...Pedantically, it's protocol 41, not port 41, that's blocked. The protocol number is in the IP header. The port numbers are in the headers of the TCP or UDP packets which are payloads of the IP packet.<br /><br />Still, well done for getting it working and thanks for telling about it.<br /><br />What I'm wondering is if there are any cheap off-the-shelf routers that support IPv6 yet. I'll need another Wifi router or two soon and it seems silly to buy one which only supports IPv4. Ideal would be one that supports tunnelling as well.Ed Davieshttp://edavies.me.uk/noreply@blogger.com
