Sorry I didn't specify my question more accurately. Of course I have used dummynet and I have also found some rules on the Internet. But unfortunaletyl none of them worked. Something like this for example: ipfw add queue 1 ip from any to 10.1.2.0/24 ipfw queue 1 config weight 5 pipe 2 mask dst-ip 0x000000ff ipfw pipe 2 config bw 300Kbit/s Doesn't work thow... So what I am asking for is not theory, but I am asking someone, to whom it actually works! I have been trying tons of different possibilities, but didn't get the right one.. I believe, someone had to face this problem before, so please help. I really don't know what to do... Thanks.
