Hi All,
I am trying to get some Web page on a IPv6 host by
using an OPenBSD 4.7 as a router. I can get the Web page
from the router but not from a host in the local net.
I have tried with OpenSolaris machine and Windows 7 machines.
At the same time the similar commands with one address hangs
and with an other address just get the page.
The bug is quite easy to reproduce. On a web browser,
getting page at the address "http://www.tunnelbroker.net"; fails
while "http://www.freebsd.org"; succeed.
The following commands allow to reproduce the problem from the command line:
1) wget --prefer-family IPv6
http://www.kame.net/~suz/freebsd-ipv6-config-guide.txt
2) wget --prefer-family IPv6 http://www.freebsd.org/index.html
The command 1 hangs, the 2 succeed.
I have tried with and without PF but the result is always identical. By
passing the command
1 directly on router it succeed. By using IPv4 address, I have no problem at
all.
I use a gif tunnel to get the IPv6 connectivity.
Any ideas would be greatly appreciated.
best regards,
Here are some traces done during the execution of different commands
