I have used my IPv6 tunnel on my stock firmware fine for months now. There is finally a stable version of DD-WRT for the e4200 router, and Ive made the switch.
Unfortunately, following the above script, after the router reboots, I do not have a WAN IP (ipv4) from my ISP.
Removing the script and rebooting brings it right back.
I'll continue to read all the posts and forums, and if I find anything, Ill remove this post, but I appreciate both the script and any help
Thanks!
Running Firmware: DD-WRT v24-sp2 (12/12/11) big
Brainslayer build
This doesn't work for me. I've followed the wiki entry to a "T" and although it looks like it's started the script I think the APIs for TunnelBroker need updating.
This is all I get in the ipv6.log. None of the other files are created.
HE IPv6 Script started
User added addresses cleaned/checked
Cron script created, sending endpoint update request to HE
Ok, now I don't have IPv6 anymore. I'm back to where the ipv6.log file stops at
"Cron script created, sending endpoint update request to HE"
It's not generating radvd.conf settings, or anything else that happens beyond that point in the script. I can't find any errors or notes to tell me why.
After a long time away from this. I've updated the script.
I've fixed the blocking issues that prevented the script from updating the endpoint. HE now requires the wan side be pingable inorder to verify the ip address. This will create an iptables rule that will allow the wan ip ping ONLY from the HE.net verification server. Everyone else will still be UNABLE to ping your wan ip, don't fear.
I also added the option to generate a wanup script that will automatically update both local and remote endpoints in case of wan status change.
Lots of little polishing throughout the script as well.
As always, I'll try to answer any questions as best I can. To the few that posted above, if you ever read this, try this new version and see if it helps.
first thanks for your details info about the IPv6 setting.
i used my WNDR3700 to follow up your setting and works very well last night.
And i like to set my router to reboot everyday at 6AM.
This morning i try to ping ipv6.google.com without luck. So i swich to HE webside, My dynamic IPv4 address is showing at HE webside.
Then i tried to reboot again, but still failed. But sometimes it will succeed.
nslookup as following:
Quote:
C:\Users\xxx>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: 2001:470:20::2
Sorry that i am newbie to community, Could you pls help to advise how to fix my problem?
thank you for this awesome tutorial, it works like a charm, for a while that is. after an indeterminate amount of time IPv6 goes away and I'm left with ipv4 only working on the lan computers. not sure what causes this, any pointers on where to look would be much appreciated, thank you.
steps :
setup this script
reboot router
ipv4 & v6 are working I can check my ipv6 IP and it shows on online ip checking sites.
wait a while(usually a few hours), go back to same site and now there's no more ipv6, I have tried to check using an IPv6 only site and there's just no ipv6 connectivity.
*Edit forgot to mention, there is still a vlid IPv6 address assigned to my adapter, so maybe the "tunnel" is collapsing somewhere or timing out maybe with lack of use?
Sorry, I have switched to PfSense several months ago so I no longer have a dd-wrt box that I use. And as such I cannot effectively help troubleshoot or maintain the script with. if anyone else would like to take up the script, please feel free to do so.
kingpin, in your case I'd check the running processes list and see if radvd is still running. I'd also try running the startup script again. There is a way to pull the script from the nvram, or you can just copy and paste the script from webconfig into a new file and run it that say. see if that helps. try http://test-ipv6.com/ maybe the detailed results could give more insight.
iTTT: that's a very odd problem, rebooting the router should rerun the script in its entirely. if it worked the first time, it should work all successive times. I'm sorry, but I'm not sure in your case.

Script works perfectly, on my ASUS N13U B1 running DD WRT Firmware: DD-WRT v24-sp2 (07/20/12) std. I get full IPv6 marks on the tests.
The only issue i have faced so far with the script is that if i do a hard reboot, the script does not work and i need to re enter the script and reboot again.
Apart from that, made one small change to the script ie instead of open dns, went for google dns & removed the logging.

Posted: Thu Oct 11, 2012 3:06 Post subject: Gateway Issues
Using the above script and the older one has had me having payment gateway issues. After the details are sent, it gives me errors and so have stopped using it since here in india we follow a slightly differant payment system.
