I want to use ipfw+dummynet. Solutions is to pass traffic that match
an rule to multiple pipe or queue with different weights. But how?
What is the precedence? (need sysctl net.inet.ip.fw.one_pass=0)
If any have an solutions please be explicity. I dont want to be easy,
but is significant in this case, in wich order apply rule, and how is
configured pipe and queue. For this reason, solutions please put in this form (example):

#section pipe and queue configuration
ipfw pipe 1 config .....
ipfw queue 8 config weight 3 pipe 6 ....

#section ipfw rules
ipfw add pipe 1 {match hight pri.}
ipfw add pipe 5 {match low pri. 300k same bandwith}
ipfw add queue 3 {match for hight pri. 512k same share}

I work for a time with dummynet. In this
example have an important to build some hierarchy with dummy.

P.S. this scheme is not changeable. Please refer to this situation.

                                            Thanks in advance!
