I'm missing something on Android passthrough

[sempf]

I have a MK4 on 2.8.1 and when I USB connect my Cyanogen phone, I get an IP on the main control panel, can check for updates, etc. I have JUST recently factory reset the MK4 after a long gap in use that led to me forgetting passwords, etc.

When a wireless user connects via karma or directly to the AP, their connection shows up in the log, and they get an IP, but they can't see the Internet.

Is there a step I am missing that allows the passthrough? I haven't tried anything because I don't know what to try. A twitter follower (https://twitter.com/W9HAX/status/649056274756304898) suggested IP Passthrough but that didn't work. Something else I am missing? Something I can check? I'm out of ideas.

Thanks.
