>Description:
The man page says

"
     Additionally, sets of alternative match patterns (or-blocks) can be con-
     structed by putting the patterns in lists enclosed between parentheses (
     ) or braces { }, and using the or operator as follows:

           ipfw add 100 allow ip from { x or not y or z } to any
"

but when I use

root:goffredo[627] ipfw add 2 count tcp from any to '(' any 22 to any 23 ')'
ipfw: missing ")"

root:goffredo[628] ipfw add 2 count tcp from any to \( any 22 to any 23 \)
ipfw: missing ")"

root:goffredo[629] ipfw add 2 count tcp from any to '{' any 22 to any 23 '}'
ipfw: missing ")"

root:goffredo[630] ipfw add 2 count tcp from any to \{ any 22 to any 23 \}
ipfw: missing ")"


>How-To-Repeat:
