Speaking of which, has anyone else noticed AT&T mobile is blocking ssh
(outgoing 22/tcp) connections? AFAIK, AT&T mobile does CGN. It's
puzzling that they'd block outgoing ssh when there have been multiple ssh
clients in the Apple app store for years. I used to be able to ssh from
my AT&T phone. I found recently, the packets don't get to the server
unless I VPN from the phone first (or am on wifi, not relying on AT&T for
IP).
