ipfwSkel creates skeleton ipfw dynamic rulesets which may be useful for the overworked sysadmin. It's not particularly clever, but does support single queue creation,

Usage: ipfSkel.pl Options: --tcp tcp ports to open to the world --udp udp ports top open to the world --trusted trusted ip or netrange to allow complete access --queue allow inbound tcp destination ports (bandwidth limited) --limit associated limit in kbits/sec for --queue ports --icmp icmp codetypes to allow (defaults to 3,4,11)

Example: Open ports 22 to the world and trust 1.2.3.0/24 ./ipfwSkel.pl --tcp 22 --trusted 1.2.3.0/24 > ipfw.rules

Create a 300kbits/sec limit for port 80 ./ipfwSkel.pl --queue 80 --limit 300 > ipfw.rules
