The wiki is primarily used as a place to brainstorm ideas. (The page name
is unfortunate as it gives the impression that it's a reference. It's
not. The warning at the top is entirely too small...)
The apparmor.d(5) manpage describes the policy language.
There's currently no way to deny specific network operations, such as bind
or listen or connect, on IP protocols. Hopefully we'll one day be able to
support more fine-grained networking rules, in which case we hope the
language will look about like the wiki page, but that's still in the
The best you can do is disable inet or inet6 entirely with the deny rules.
