Firewall blocks ssh since Sept 12 update

Question

I have a Mac Pro Early 2008 running Lion 10.7.1 (11826). Since the "Security Update 2011-005" yesterday morning (Sept 12), the firewall does not allow incoming ssh connections, even though "remote login" is enabled in the "Sharing" preferences pane, and the firewall config page under "Security & Privacy" shows that "Remote Login (SSH)" is set to "Allow incoming connections". I do this all the time, and the behavior definitely changed with yesterday's update.
To be clear, with the firewall turned off, I am able to ssh into the machine from another machine on the local network. When I turn the firewall on, despite the options set as described above, I am unable to make an ssh connection. This worked before yesterday's update. I think that Apple broke something with the update.

Answer 1

Okay, I just found out you have to query anchor rules with a special switch (-a).
I just found out there is no entry for SSH which should read something like
"pass in on inet proto tcp from any to any port ssh keep state"
euler:~ dr$ sudo pfctl -a "com.apple/100.InternetSharing" -vvvsr
No ALTQ support in kernel
ALTQ related functions disabled
euler:~ dr$ sudo pfctl -a "com.apple/250.ApplicationFirewall" -vvvsr
No ALTQ support in kernel
ALTQ related functions disabled
