I just spent a few minutes looking into this again, and figured out the
problem. AT&T has apparently changed the way their CGN works. I use a
form of port knocking to restrict access to SSHd from "foreign" networks.
It used to work fine from my phone. Now, the port knocking request from
the phone and the ssh connection are being NAT'd to different public IPs,
so my system is allowing ssh access to one AT&T IP, and then the ssh
connection comes from a nearby but different IP.

Not here, have an SSH session open on my phone on port 22 as we speak. I'm on
an android on ATT's 3G network in central indiana, if that matters.
