Re: [IPv6] IPv6 Comcast Speedtest

Ok I saw that, but it just looked different then what I see when I go to that page is all, which is why I asked.

And, I see you can get to Google's IPv6 site, so that means IPv6 is indeed working for you. Sorry if I made it out like that was the problem, I just did not think it was based on the results you had provided (again, being different from what comes up on the screen for me on those two sites).

What happens if you try to do a trace route to the Comcast IPv6 speed test site? My results are below

tracert ipv6.speedtest.comcast.net

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.

Just making sure that you know you're using an IPv6 tunnel to SixXS and not Comcast native.

Are you sure that IPv6 is working for you?

Can you get to these two sites, and what are the results?

I can get to the »www.test-ipv6.comcast.net/ site, and I get two 10/10's. I cannot get to the Comcast IPv6 speedtest site, though. It just times out.

I wonder if Comcast is restricting their speedtest site to Comcast IPv6 only --- I am using a he.net tunnel for IPv6.

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.

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.

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.

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.

Sometimes the site start page would load, but the test never worked. The actual speed test would either never start or it would hang busy and never finish. If you don't have native IPv6, that test site appears to be useless.

Yes, had it backwards. 2001 on the WAN side, 2601 on the LAN side. I still couldn't get it to work right, so I set my router to 6to4 Tunnel and tried the readiness site, and it worked, so I changed it back to DHCP, and got the IPV6 addresses again, and now I'm fine. Readiness 10/10, speedtest 52 down/10.5 up (Blast).

What type of router do you have? Sounds like you had to reset your settings to clear your DHCPv6 info. A little odd me so I would like to look into this.

Router Type and version would be great start.

My guess would be a Netgear router. I have to reboot my WNR1000v2-VC about once a week because it loses IPv6 sync. The router's WAN and LAN, and attached devices still have valid looking IPv6 addresses, but they don't work anymore until I reboot the router, and it gets (and redistributes to its LAN devices) new IPv6 address assignments from Comcast.

I don't believe it is a general problem, it works just fine for me through a HE tunnel.

Thanks... I am willing to work with whoever to torubleshoot why this is happening. Might very well be an issue on my end but I can do traceroutes and pings from looking glass sites back into my host.

For some reason the thought of using a COmcast looking glass site had not occurred to me if such a thing is available.

Guess I should have started with the basics. Was assuming that I was even hitting your server in the first place when I was getting the connecting then the waiting in the browser. However, the traceroute shows a different story.

More specifically OCCAID (his tunnel pop) doesn't peer directly w/Comcast and their TATA link is really congested.

There are a couple more traceroutes that I sent to NetDog via IM. When I clear DNS and try again I get a different ip almost every time. Some of the IP's traceroutes work and some do not. However, the web page never loads even if I leave it for 20 minutes. I have done some packet captures where the initial tcp handshake goes through but when the http get is done by the browser the comcast server never replies.

Maybe a return path routing issue?

Have a Linux box with tracepath6? I'm guessing PMTUD issues.

Yes, had it backwards. 2001 on the WAN side, 2601 on the LAN side. I still couldn't get it to work right, so I set my router to 6to4 Tunnel and tried the readiness site, and it worked, so I changed it back to DHCP, and got the IPV6 addresses again, and now I'm fine. Readiness 10/10, speedtest 52 down/10.5 up (Blast).

What type of router do you have? Sounds like you had to reset your settings to clear your DHCPv6 info. A little odd me so I would like to look into this.

Router Type and version would be great start.

My guess would be a Netgear router. I have to reboot my WNR1000v2-VC about once a week because it loses IPv6 sync. The router's WAN and LAN, and attached devices still have valid looking IPv6 addresses, but they don't work anymore until I reboot the router, and it gets (and redistributes to its LAN devices) new IPv6 address assignments from Comcast.

Yes, it is a Netgear WNDR3400. I've had this problem before, and switching it to tunnel and back again fixes it. Don't have to reboot, but still, it shouldn't be happening. My symptoms are the same as yours (IP6 addresses all look good, but IP6 doesn't work).

What version of OS do you have on the WNR1000v2-VC, I will start asking questions..

Here is the OpenWRT [KAMIKAZE (7.09)] OS version information:
Linux version 2.6.15 (chao.zhang@dni-l-sw01) (gcc version 3.4.4 (OpenWrt-2.0)) #199 Tue Apr 17 12:29:38 EDT 2012

Here is the Comcast/Netgear firmware information:
Hardware Version: WNR1000v2-VC
Firmware Version: V1.2.2.56NA
GUI Language Version: V1.0.0.71

EDIT:
If you are going to be bugging the Comcast/Netgear WNR1000v2-VC firmware writers, please also ask them to fix the bug that was introduced with Firmware Version: V1.2.2.56NA that prevents doing port forwarding for port 80 if Remote Management is enabled. It does not matter what port is used for Remote Management; if it is enabled, you can't do port forwarding for port 80 (DMZ also blocks inbound port 80 if Remote Management is enabled). There is also a long standing bug in all of the WNR1000v2-VC firmware versions that prevents UDP port 123 from being port forwarded as well (that also does not work with DMZ either).
