Thanks to Luigi. > YES IT WORKED YES thank you VERY MUCH for the kind help and for making it clear all the stuff I missed reading, yes I assume I should have read more or at least understood now I can see how the things works and it does work THANK YOU again very much > Now its time to have some fun: > > ipfw/ipfw add pipe 1 all from 172.16.251.0/24 to 172.16.251.0/24 > ipfw/ipfw pipe 1 config bw 128Kbit/s delay 300 > > and now ping machine-A and machine-C and see dummynet working as > expected... > > I believe you can keep on with your testings now!!! :-) > yes it worked as well now let me ask you all, other than click, does netmap offers something that can do packet forwarding? simple packet forwarding like the scenario I was trying before?
