# allow DNS,NTP queries out in the world
add pass udp from any 1024-65535 to any 53,123
add pass udp from any 53,123 to any 1024-65535
add pass udp from any 53,123 to any 53,123
add pass tcp from me to any 53 setup keep-state

Note that you probably want to use the combination of "setup keep-state" 
elsewhere in your rules, too.
