No route to host ... can you ping6/traceroute6 to www.kame.net? Can
you reach it with: telnet -6 www.kame.net 80 ?

Your connectivity to there seems to be foobared if you'd ask me as:

bz:~> telnet -6 www.kame.net 10000
Trying 2001:200:dff:fff1:216:3eff:feb1:44d7...
telnet: connect to address 2001:200:dff:fff1:216:3eff:feb1:44d7: Connection refused
telnet: Unable to connect to remote host

I get the connection refused.
