I was able to enable IPv6 through the web interface when I used an EdgeRouter about a year or so ago. Even some of the Wizards turns it on for you if you want (IIRC) although you can go into the manual configuration to set it up. I ended up switching to Microtik due to my unease with Ubiqiti. Have to say however I found it more difficult to set up IPv6 on the Microtik, so another point for the EdgeRouter's IPv6 support there.
