IPv6 setup Hurricane Electric Tunnel Broker
From DD-WRT Wiki
This will...
Set up HE's tunnel broker service.
Automatically finds your wan ip at boot using whatismyip.com
Automatically updates HE's endpoint on boot
Generates a radvd.conf on boot, and applies it automatically
Generates a executable file that can be used with cron to keep HE's endpoint up-to-date if you have a dynamic IP
My setup for reference.

You should have an account and tunnel created on the website. This post will not cover that. Install steps are below the script.

Installation steps:
- Change the settings in the beginning of the above script to your settings.
- Copy personalized script into Administration > Commands. Save as startup script
- Go into Administration > Management
- enable IPv6 and radvd. Leave the config box empty
- (Optional) enable cron and enter this into "Additional Cron Jobs"
Code:
* 4 * * * root /tmp/report.sh
The above line will auto update the endpoint daily at 4am. Change to personal taste
- Apply settings, wait for reboot
