Trace complete.
 

I will say though, after paying closer attention, that the test is doing something weird. When doing the IPv6 portion, the v6 IP it shows keeps alternating between my host IP and the IP of my router and eventually the final is the router IP. THat may have something to do with it.

Will keep looking.

Yeah, that does not sound right. I know if I go to this page

»www.test-ipv6.com/

and reload it over and over, I always get the same IPv6 IP being shown, which matches what my Windows 8 Desktop reports as the "Temporary IPv6 Address" shown when I run an ipconfig/all.

I think Comcast is having IPV6 problems today. I can't get to the IPV6 speedtest site, and I have been able to in the past. Also, the readiness check shows that ipv6 sites are all timing out, and I get 0/10 where I previously had 10/10. My router does show DHCP with an IPV6 2601: address on the WAN, and 2001: on the LAN, so that part is working.

Okay...this may or may not be related. I set up a tunnel via HE and I seem to have lost it. I double checked all of the settings including the IP address from Comcast and it's all correct on HE's site and my router.
So are there people out there experiencing the same with their IpV6 tunnels or is this just happening with native IPv6? I don't have native IPV6 due to the on going work with Comcast and Cisco. I have a DP3008 modem. Thanks.

I have two he.net IPv6 tunnels, both are working fine.

Well, I just checked things on my end.

For my router (PFSense 2.1 beta build) I am getting on the WAN side an IPv6 IP of 2001:558:.... The subnet mask on the WAN side is 128. For the LAN side, the IPv6 IP is 2601:d:4c00.... with a subnet mask of 64.

I can get to all three of these pages without problems
Comcast's IPv6 Speed Test: »ipv6.speedtest.comcast.net/
General "Test Your IPv6" site: »www.test-ipv6.com/
Comcast's IPv6 Test site: »www.test-ipv6.comcast.net/

Both of the test sites return 10/10. The IPv6 IP that is shown on all three is the same, and is 2601:d:4c00..... That also matches exactly what my ipconfig/all shows for my "Temporary IPv6 Address" on my desktop (which is the computer that I accessed all sites from).

So, as far as I can tell, things are working the way they should be for me, and without any problems.

It must be on my end then. Guess I have to do a little more diagnostic work. Thanks. If I can't get it to work I'll just delete it and reconfig it.

Edit...I figured out my problem with the HE Tunnel. I Googled my problem and found out when I up graded my AEBS to v.7.6.3 is broke the tunnel path. I down graded back to 7.6.1 and everything works fine again. So until Apple gets their act together on a fix. I'll leave as it.

I just tried this site: »test-ipv6.iad.vr.org/ and it comes up with the correct IP.

If I use: »www.test-ipv6.com/ it has the back and forth and ends on an incorrect IP. The IP it ends with is my tunnel end point.

Ok, so I just tested at about 8 other sites and they all came up correctly. So the one site is the anomaly.

When I try and access the speedtest, my browser says it is connected and waiting for the site to respond. So the initial sync/ack handshake works but then it dies.

Do you have that backwards, or is something wrong with my info? I have a 2001: address on the WAN side, and a 2601: address on the LAN side. Yours seems to be the other way around!

So, just wanted to point that out, in case yours (or mine) is incorrect, or if it was just a typo on your part.

Any comment on why the speedtest does not work for those of us on a tunnel? Has it been setup for comcast users only in Comcast IPv6 address space?
