still unclear though, how are your clients connected to the dummynet bridge ? unless they are one on each port, how can you insure that the traffic between any pair goes through the dummynet box ? Ok, what you want is to use multiple cascaded pipes (for which you might try the patch that you mentioned in your previous email). cheers luigi On Thu, May 30, 2002 at 12:39:19AM -0700, Jon Noack wrote: ... > > this particular example is probablu even on the ipfw manpage > > or on the dummynet page > > http://info.iet.unipi.it/~luigi/ip_dummynet/ > > Yes, this is the functionality I have.
