First and foremost, I take no credit for any of this post’s content. I am really just taking what others have done (which I have links to bellow) and am putting it on my blog for a personal reference and hopefully the small changes that I made to their guides will help someone somewhere.

On switchless devices, simply bridge all ethernet interfaces together, remove the existing WAN interface - if any. On devices where WAN and LAN are separated by switch config, reconfigure the LAN VLAN to cover all ports, remove the existing WAN interface and its related VLAN - if any. If you would like your AP to receive IPv6 as a host only and not for routing you have to tell dhcp6c not to request prefix deligation. If you do not do this the AP will reject basic IPv6 addresses.

Then login with your root password at luci interface. It is not very safe if you have an hacker close to you, but is very handy.
