I don't know. I just tried it again and it is working. I think your PC doesn't get IP6... For me, now it is only working with radvd. Did you updated your IP on tunnel? Do you have dynamic IP?

tunnel has the correct ip, its something with the router as its not giving me ipv6 anything no ip, dns..all the pc has is link local ipv6 which is useless. theres a router ipv6 address setting in ipv6 but i dont know whats supposed to go in there (shouldnt there be a default supplied?), & theres no ipv6 local settings like there is for ipv4

if you don't enter it (router ipv6) you will be assigned from tunnel broker ... for me it is working without entering it... It is very hard to troubleshoot your problem 'cause we are not on the same kernel? Just try with radvd, or even with DNSmasq... your ipv6 works because you can ping ipv6.google.com from router... your clients doesn't get ipv6 stuff (ip, dns etc) so IMO that is problem...

save settings then more will appear


I didn't think about that. Embarassed I figured it would just auto-populate the extra fields. Thanks for that.

This works great on my Netgear WNDR3700v1, much easier than the script.

I have the same problem using build 25697 on my TL-WDR4300 v1.3; radvd doesn't seem to start from the GUI.

When I fall back on my previous HE IPv6 script, ipv6 works and radvd is running (on the command line: ps | grep radvd).

Maybe you should write a ticket, because it is not working for two of you... In one of the previous builds it wasn't working for me either so I started to use dhcpv6s... it was just one click, enable, and it start working... I never wrote ticket because I wasn't sure... BS almost always says it bull... and 90% he is right. so I tried to avoid that:)

On Security tab uncheck Block Anonymous WAN Requests (ping)... but it will allow all icmp... consider to add exception for just that IP... you will have to do it from command tab (add iptable rule)...

You use
iptables -I INPUT 2 -s 66.220.2.74 -p icmp -j ACCEPT
to accept icmp from HE.
But how did you know that IP address was the one to use?
It seems to be the address of arc.he.net

I find it works fine without anything entered as the static DNS 1 or 2.
Presumably this is because the IPv4 DNS I use also has IPv6 connectivity. (I use OpenDNS)

when creating tunnel I got this message:

IP is not ICMP pingable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall.
