pass in/out proto tcp/udp from xxx to xxx port 1024 >< 4000
if u use tcp , please add flags S keep state
if u use udp , please add keep state
if u use tcp/udp , add keep state
ex.
pass in proto tcp from 192.168.0.0/24 to any port 1024 >< 4000 flags S keep state
if u have any questions,please look ipfilter's documents.^^
