freebsd shaper

[Aleksandar Simonovski]

Hi,
This is my scenario, now it is working on Slackware 9.1 with CBQ
but i wanna do it on FreeBSD 5.1

   1.---------
		| 
   2.---------   
		| <-------> HUB <-----> ETH1 <--- SHAPER ---> ETH0 <-----> INTERNET
   3.---------
		|
   4.---------

1,2,3 and 4 are all different networks 
1 has  192.168.0.199/24 that is 192.168.0.199 is alias on ETH1
so a need NAT for this one.
ETH1 has four aliases which are gateways for 1,2,3, and 4
this is working on the linux box but i have some troubles with limiting thr traffic with CBQ
so am asking if anyone knows how to do this on FreeBSD 5.1 with IPFW and DUMMYNET

thaks,
Aleksandar
