Are you sure that the UID is correct ? What kind of traffic are you
trying to match ?
Keep in mind that --uid-owner matches the effective UID, so packets sent
by special programs with the SUID bit set such as ping, traceroute...
have the UID of the owner of the program (usually root).

I don't know.
