This gist explains how to set up IPv6 connectivity on your Ubiquiti UDM Pro or similar Ubiquiti devices using a Centurylink 6rd tunnel. Enable free IPv6 access to your network without relying on ISP support.

Forked from a lot of hard work done by Ben Grewell - Here: https://gist.github.com/bgrewell/faee67342085fb8fe98b446feeb10ced
