UniFi Tunnelbroker Configuration

This GitHub Gist details the manual configuration needed on a UniFi controller to enable IPv6 tunneling with Hurricane Electric's Tunnelbroker service.

Setup

This is what works for me personally. Stuff you'll need to do to adapt this to your ends:

• Replace "local-ip" with your USG's public IPv4 address.
• Replace "remote-ip" with the address of your Tunnelbroker tunnel server.
• Replace "address" with the IPv6 address that your are allocated.

Installation

Follow these instructions and drop your config.gateway.json file in the correct location e.g. /usr/lib/unifi/data/sites/$NAME/.
