Maybe someone can help me figure this out.

I have my tomato rt-n16 router on dmz+ in my old non ipv6 cable modem.
In tomato the ipv6 page has a few options. I have already created a tunnel on HE.
What am I missing.

Options for ipv6 drop down menu:
1. Disabled.
2. Native ipv6 from isp.
3. DHCP with prefix delegation.
4. 6to4 anycast relay.
5. 6in4 Static tunnel.
6. manual config.

I presume the 6in4 tunnel is what I need.
This has a few sub options.
1. Assigned / Routed Prefix                             2001:470:1f05:1e45::
2. Prefix Length                                             64
3. Router IPv6 Address "manual or default"       2001:470:1f05:1e45::1  "Default"
4. Static DNS                                                2001:470:20::2
5. Enable Router Advertisements                     x
6. Tunnel Remote Endpoint (IPv4 Address)        72.52.104.74
7. Tunnel Client IPv6 Address                          2001:470:1f04:1e46::2
8. Tunnel MTU                                               0
9. Tunnel TTL                                                255

How does the HE tunnel details page info related to these options, same as I have above from below ?

Test Tunnel info:
Server IPv4 Address:72.52.104.74
Server IPv6 Address:2001:470:1f04:1e46::1/64
Client IPv4 Address:189.170.xxx.xx
Client IPv6 Address:2001:470:1f04:1e46::2/64
Available DNS Resolvers
Anycasted IPv6 Caching Nameserver:2001:470:20::2
Anycasted IPv4 Caching Nameserver:74.82.42.42
Routed IPv6 Prefixes
Routed /64:2001:470:1f05:1e45::/64
Routed /48:

The settings you've entered look correct to me. I use Tomato-RAF on my router and the layout is the same. Just choose 6in4 Static Tunnel and if you're on a dynamic IP address, don't forget to configure the DDNS page with the HE details.

I know this is an old thread, however I'm having some issues with this as well.  My router can access IPv6 perfectly fine.  My clients are even receiving both 2001 and fe80 addresses, however I can not for the life of me get the to talk to any ipv6 based addresses.  ipv6-test.com says I don't have an ipv6 address (from my client), but that my DNS is connecting to IPv6 just fine.  Now my ISP doesn't support IPv6 so I know the DNS support is coming from the router.  How on Earth do I get my clients to connect to the outside world via IPv6?

shouldn't the tunnel mtu be 1480 or 1472 for pppoe connections?

This is almost certainly a factor of your MTU. If you're on linux you can use tracepath to estimate your MTU. If you're on Windows, try mtupath

It can be confusing figuring out which IPs go where, so I created this guide.

Thank you so much!

Your guide was extremely helpful. I had everything except the "Router IPv6 Address" settings correct which was causing all my ip tests to resolve to the local router. If I hadn't found this, I'd still be experiencing weird issues. A moderator should really consider adding the instructions and this graphic ( http://troywitthoeft.com/wp-content/uploads/2012/02/IPv6-HE-to-Tomato.png ) to the official example configurations.

Thanks ^^

Your graphic looks correct. Though I think it would be a good idea to fill in all three DNS server fields. You could for example use 2001:4860:4860::8888 and 2001:4860:4860::8844 for the second and third DNS server.
