Set up tunnel to HE.net and now only ipv6.google.com works, but other sites ping fine.
- by AndrejaKo
I'm setting up IPv6 using my router which is running OpenWRT, version Backfire 10.03.1-rc4.
I made a tunnel using Hurricane Electric's tunnel broker and set it up on the router and I'm using RADVD to hand out IPv6 addresses.
My problem is that on computers on the network, I can only access ipv6.google.com using a browser, but other sites seem to be loading forever and won't open in any browser. I can ping and traceroute to them fine, but can't open them with a browser.
I can open any site normally with a browser from the router.
Stopping firewall service on the router doesn't help, so it's probably not a firewall issue.
All AAAA records resolve fine, so it's probably not a DNS issue.
Computers on the network get their IPv6 addresses fine, so it's probably not a radvd issue.
Similar setup worked fine for SixXs, but I'm having problems with my PoP there, so I decided to move to HE.
Here are some traceroutes:

I have computers running windows 7 SP1 and openSUSE 11.3 and all of them have same problem.
I also made a thread about this on HE's forum, but it seems that people there are out of ideas what to do.
