I am typing this, because there is a lot of misinformation on this, especially about the dynamic DNS part.

The tunnel

Go to the router web panel and IPv6 under advanced settings.

Basic Config

  • Connection type: Tunnel 6in4
  • Server IPv4-address: Server IPv4 Address from IPv6 tunnel endpoints in tunnelbroker.net tunnel details
  • Client IPv6 address: Client IPv6 address from IPv6 tunnel endpoints in tunnelbroker.net tunnel details
  • IPv6 prefix length: 64
  • Tunnel MTU: 0
  • Tunnel TTL: 255

IPv6 LAN Setting

  • LAN IPv6 Prefix: Routed /64 from Routed IPv6 Prefixes from tunnelbroker.net tunnel details
  • LAN Prefix Length: 64

IPv6 DNS Setting

  • IPv6 DNS Server 1: 2001:470:20::2 (this is the one tunnelbroker.net says for me)
  • IPv6 DNS Server 2: 2001:4860:4860::8888 Google DNS 1
  • IPv6 DNS Server 3: 2001:4860:4860::8844 Google DNS 2

Auto Configuration Setting

  • Enable Router Advertisement: Enable

Dynamic DNS

Go to Advanced Settings, WAN, DDNS

  • Enable the DDNS CLient: Yes
  • Server: WWW.TUNNELBROKER.NET
  • Host Name: tunnel ID from tunnelbroker.net tunnel details
  • User Name or E-mail address: *username of tunnelbroker.net
  • Password or DDNS Key: Update Key from tunnel details under the Advanced tab

All guides I have seen say that username is user ID from index of tunnelbroker.net and password is account password, but that doesnt work for me. This is how I got it working guessing the details based on Example Update URL at the same place you got the Update Key.

Now it should either work or not.

  • If it gives error saying something about trying again later, you are doing something wrong.
  • If it gives error about endpoint IP not changed since the last update, it works.
  • If you dont get error, it doesnt work.

Now I would suggest you to go to Administration and from there Restore/Save/UPload Setting and clicking the “Save setting”s “Save” button so in case something bad happens you can easily restore the working state.

And I probably shouldnt need to say this, but I will say it anyway: dont use admin/admin as username/password combination!
