Title: IPv6 Test Good, But Can't Connect To Sites
Post by: solidus on August 14, 2012, 10:35:21 PM
I recently started using the HE tunnel. I've used the example configuration for Windows 7, but cannot reach any sites.

I've gone to http://test-ipv6.com/, which says that I have 9/10 for IPv6, with one error about DNS. Going to http://whatismyipv6.net/ says I don't have a v6 IP. Afterward, I try going to http://kame.net, but it doesn't work.

Here are the results of its test.

Code: [Select]
Test with IPv4 DNS record  
ok (0.157s) using ipv4
Test with IPv6 DNS record  
ok (0.132s) using ipv6
Test with Dual Stack DNS record  
ok (0.101s) using ipv6
Test for Dual Stack DNS and large packet  
ok (0.059s) using ipv6
Test IPv4 without DNS  
ok (0.060s) using ipv4
Test IPv6 without DNS  
ok (0.047s) using ipv6
Test IPv6 large packet  
ok (0.049s) using ipv6
Test if your ISP's DNS server uses IPv6  
bad (0.073s)

Here's my IPConfig.

Code: [Select]
Ethernet adapter FiOS:

   Connection-specific DNS Suffix  . : home
   IPv6 Address. . . . . . . . . . . : 2001:470:d:71f::1
   Link-local IPv6 Address . . . . . : fe80::956:b4d1:15c4:538a%10
   IPv4 Address. . . . . . . . . . . : 192.168.1.2
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1

Tunnel adapter IP6Tunnel:

   Connection-specific DNS Suffix  . : home
   IPv6 Address. . . . . . . . . . . : 2001:470:c:71f::2
   Link-local IPv6 Address . . . . . : fe80::f546:fc17:6a18:b2af%37
   Default Gateway . . . . . . . . . : 2001:470:c:71f::1

I'm behind a NAT, and I've set my router to forward Protocol 41 using this guide.

I used 192.168.1.2 as the IP which corresponds to the tunnel, again because I'm behind a NAT.

What should I try next?

I checked out the webpage you referenced and I'm not sure what to think.

My immediate reaction is the webpage is wrong; he clearly states that he enters 41 in the "port forwarding box".  We aren't trying to forward a port, we're trying to forward a protocol; port != protocol.

If you want my two cents, your firewall is blocking protocol 41.  To refute or confirm that, start looking at packets and see what's going on.

What's a good way to do that then.

Grab some packet sniffing software like wire shark and have at it.  There should be a bunch of tutorials on google

Okay, I installed Wireshark and used ip proto 41 as the filter that I got from here http://wiki.wireshark.org/IPv6.

These are the errors, which are about SSDP, TCP, and HTTP having a bad checksum.

There are also green (okay) segments when contacting http://ipv6-test.com/. I think that Protocol 41 is forwarded, but there's probably something missing from my configuration.
