IPFW do FreBSD não limita a velocidade!!!!

[CEP]

Olá pessoal!!! estou com problemas na limitação de banda para os clientes via IPFW do FreeBSD 5.3. Quando meço a velocidade de conexao do cliente no gratis bate la em cima, tipo 460kbps, 680kbps... sendo que no servidor estão todos barrados em 240kbps. vou postar meu ipfw.rules ai em baixo. Se alguem puder me ajudar, desde ja agradeço a atenção.

ipfw -f flush
natd -s -p 8668 -n tun0
ipfw add 10 divert natd all from any to any via tun0
ipfw add 11 allow all from any to any via tun0
ipfw add 12 permit all from any to any via rl1
ipfw add 13 deny udp from any to any 137
ipfw add 14 deny udp from any to any 138
ipfw add 15 deny udp from any to any 139
ipfw add 16 fwd 127.0.0.1,3128 tcp from 192.168.0.0/24 to any 80

ipfw add 20 allow ip from 192.168.0.1 to any
ipfw add 21 allow ip from any to 192.168.0.1
ipfw add 22 allow ip from 192.168.0.2 to any
ipfw add 23 allow ip from any to 192.168.0.2
ipfw add 24 allow ip from 192.168.0.3 to any
ipfw add 25 allow ip from any to 192.168.0.3
ipfw add 26 allow ip from 192.168.0.4 to any
ipfw add 27 allow ip from any to 192.168.0.4
ipfw add 28 allow ip from 192.168.0.5 to any
ipfw add 29 allow ip from any to 192.168.0.5

ipfw pipe 1 config bw 240Kbit/s queue 10
ipfw pipe 2 config bw 75Kbit/s queue 10
ipfw add 100 pipe 1 ip from any to 192.168.0.8/30 out via rl1
ipfw add 105 pipe 2 ip from 192.168.0.8/30 to any in via rl1

ipfw pipe 3 config bw 240Kbit/s queue 10
ipfw pipe 4 config bw 75Kbit/s queue 10
ipfw add 110 pipe 3 ip from any to 192.168.0.12/30 out via rl1
ipfw add 115 pipe 4 ip from 192.168.0.12/30 to any in via rl1

ipfw pipe 5 config bw 240Kbit/s queue 10
ipfw pipe 6 config bw 75Kbit/s queue 10
ipfw add 120 pipe 5 ip from any to 192.168.0.16/30 out via rl1
ipfw add 125 pipe 6 ip from 192.168.0.16/30 to any in via rl1

ipfw pipe 7 config bw 240Kbit/s queue 10
ipfw pipe 8 config bw 75Kbit/s queue 10
ipfw add 130 pipe 7 ip from any to 192.168.0.20/30 out via rl1
ipfw add 135 pipe 8 ip from 192.168.0.20/30 to any in via rl1

ipfw pipe 9 config bw 240Kbit/s queue 10
ipfw pipe 10 config bw 75Kbit/s queue 10
ipfw add 140 pipe 9 ip from any to 192.168.0.24/30 out via rl1
ipfw add 145 pipe 10 ip from 192.168.0.24/30 to any in via rl1

tenho tambem o incoveniente de para cada cliente na rede eu ter que colocar essas 4 linhas no ipfw.rules. Sera que eu poderia limitar toda minha rede para a velocidade "X" sem precisar colocar esse tanto de pipes? Pessoal sou novato na area.. relevem......
Aguardo respostas pessoal !!! Forte abraço.

Segue abaixo regras que ja utilizei e funcionaram 100% tanto pra down quanto pra up !!!

/sbin/ipfw add 1 pipe 3 tcp from any to 192.168.0.5out
/sbin/ipfw add 1 pipe 4 tcp from 192.168.0.5 to any in
/sbin/ipfw pipe 3 config bw 128kbit/s queue 10kbytes
/sbin/ipfw pipe 4 config bw 128kbit/s queue 10kbytes


Valeu !!!
