I experienced no similar behavior. I have a Logitech media server
(squeezebox) that opens and listens on port 9000 (internal network only
also)... and after update, it continued to work as similar.

So the question to ask is... how was your machine configured before the
update? Did you have any kind of port filtering software in place? Like
IP filters? During update, if there are configuration files that change,
the updater asks whether you want to keep, or replace (or compare first)
the original configuration file (yours) with the new (12.04) one.
Depending on how you did the update, maybe the files were replaced
automatically, or you were asked and didn't realize what happened. Have
a look in /etc for files that end in "dpkg-old"... you might find one
that could explain.

Shalom and good luck,
Gilles.
